Since there is an exhaust thread pretty much every other day, I thought it would be good to make one for those looking to make their own custom exhaust. Many people tend to go this way because the aftermarket systems for our cars are becoming more and more difficult to find. Let's begin?
What size piping would be best for my GT/ST//GT4/etc?
This question really depends on your goals for the car, and what you do with it. My typical rule of thumb that has worked best for me, is 2.5" and below for N/A vehicles, and 3"-3.5" for turbo'd vehicles. The bigger the piping on an N/A, the more bottom end you will lose, however, you will gain better top end. Find your trade off point.
What about mufflers?
This is where it gets interesting. The muffler you use will determine how your car sounds. There are many different ones out there, and different types. You can have the traditional canisters, which you see mainly in the tuner scene, then there's the Magnaflow/Flowmaster type. Here are pictures showing each:
Canister:
Flowmaster/Magnaflow:
The difference in these mufflers comes from inside. Quality mufflers will have better construction and better quality inside baffling, which will bring out nice sound from your exhaust. Cheap mufflers like the ones you see on Ebay will use sound metallic and tacky. My personal recommendation if you choose to get a canister would be either the Megan Racing N1 replica ($70-$80 on Ebay), or the OBX B10 ($50-$60 on Ebay).
How do I get the piping?
Now here comes the fun part. After you've purchased your muffler and decided on your piping size, you get the piping itself. You can buy DIY exhaust kits online, which are fine if you know how to weld, but otherwise I recommend going to a local exhaust shop. From here, you can tell them what you're wanting out of your exhaust system, plus you can customize your muffler placement/angle, as well as the design of the piping, so that you can get the most straight piping possible for your setup. I paid $130 for 2.5" piping on my Supra, this included the piping itself, a resonator, and the labor to put everything on. You will want to get piping from the cat to the back of the car. Basically they cut the piping off from where it runs into your cat, and then weld on bigger piping. Many exhaust shops will NOT condone the removing of your cat, nor do I condone it. This brings problems with emissions, as well as state inspections, not to mention your car will sound like crap. I highly recommend getting a resonator added in with your piping to ensure a better sounding exhaust, you'll be glad you did it.
Here is my final result with my Supra:
I hope this will give you guys a better understanding on what to look for and get when wanting to get an exhaust system.

Awesome write up Matt - thank you!
Niceee post!
Dont forget the Greedy (or replicas like OBX) SP2 muffler used by many owners 6gc!
Some blabla...
Let's get this stickied!
Yeah, you got a point. Everyday I see some question about exhaust in regards to piping size and mufflers. It would be nice to have a reference so people can just go right to it.
I just got the obx muffler put on last week. I did not get larger piping from the catback because it sounds exactly like the stock muffler did. I think i will upgrade to the apexi n1 universal muffler and get 2.5 inch piping done. So i hope after that it will sound decent.
what diameter piping does the 1.8 liter have? just got the car a couple months ago and thinking about getting a different muffler.
I NEVER recommend welding a new muffler onto the stock piping, you will NOT see any benefits (other then sound, if you consider that one).
I know you did not recomend it but i told the muffler shop what i wanted and they just welded it on to stock. But i did not get any sound diffrence from stock with the obx. It sounds like a prius lol. But i am thinking about going with this http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33636&viewitem=&item=180268729157&_trksid=p3907.m29 and get 2.5 inch cpiping from the ccatback..and watch as they do it this time. I think it will be diffrent i have never seen a black muffler and i think it will look pretty cool with my black celi. AND thanks for emailing that guy gotToyota..i did not mean to "shoot" the messanger.
You can go with that muffler, but you'll be getting the same results as with the OBX. IMO, it's not worth the extra $150 dollars just for a genuine Apexi. Go back to the exhaust shop, tell them you want to keep the OBX muffler, but just want 2.5" catback piping put on.
-Matt
IS it the larger piping that gives you the sound becase right now mine is silent.
who me mine sounds pretty good but i put the silencer back in the droneing sound was gettin on my nerves
yup... going catless def makes it louder... sometimes i wonder y i do things like that...
what if i went catless and got a resonater?
What will a respnater do? i dont think it cant be any quiter lol.
makes it quiter and its apart of emmisions so they arent legal to have off
Does it come stock with a resonater?
cars yes they do its like the law or something lol
Well i hope getting the larger piping will make the sound better... idk maybe my muffler is bad.
i dunno about that did you ever get the silencer out
lol yes... after about in hour of pulling/twisting and yanking it came free.
The Megan muffler, is this a noisy muffler? Or a smooth one, which makes nice sound instead of a lot of bad noise?
So when the cut out the old muffler and piping they also cut out the resonater?
no the resonators by the cat i believe its b4 it but i could be wrong my brothers 3kgt had 4 and he cut two off but he lives where emmsions dont matter
Resonators are there to... well exactly what they say - resonate. A resonated system will always sound more smooth and mellow to an identical non-resonated setup. If you're looking for rasp then a non-resonated system is the way to go. I had a non-resonated setup on my wrx and it sounded like a racecar. Swapped out for a resonated setup and it sounds much smoother now.
IIRC the stock exhaust on an ST is 2.25". If you want to increase that, 2.5" is the best way to go from what I understand.
The resonator is separate from the cat, and is somewhere before the muffler. It is NOT needed to pass emissions (I don't even think it affects it, just sound), but you will need a cat to do so.
i can't find what size the stock exhaust is for the 3sgte..
What's the largest diameter exhaust you can run over the rear axle?
That pulled up pretty nice, the first pics I saw with the flange sitting on the turbo made the gap
look a little bigger.
Here is a clear explanation of each a resonator and catalytic converter as well as their function. (courtesy of carexhaust.com)
Catalytic Converter
As already mentioned, the catalytic converter reduces harmful emissions from engine exhaust. It uses a combination of heat and metals that act as catalysts. A catalyst is a metal (or chemical) that causes other chemicals to go through a reaction without being affected itself. The inside of the catalytic converter consists of metals like aluminum oxide, platinum palladium. These metals cause the carbon monoxide and hydrocarbons to react and produce water vapor and carbon dioxide which are much less harmful to the atmosphere.
Resonator
The muffler alone cannot always quiet all of the engine noise. Many car exhaust systems also include a resonator which is like a mini muffler. They are usually straight pipes filled with sound muffling materials. The resonator can be either before of after the muffler in the exhaust system.
-Terracar
Also wanted to add, man that exhaust work looks very nice..... perhaps you could open an exhaust shop on teh side
-Terracar
Bump up.
Maybe next week the defective header i get from ebay, is repair...!
I will put straight exhaust Stainless pipe Size 2" with OBX SP2 - No Cat and no ressonator!
Lets see how this gone end...
hey matt what was the name of the exhaust shop that did your supra?
I did all of mine with magnaflow, muffer cat and res.
its 2.5 form the header going into a 2.25 all the way back
Sounds nice, any pictures?
Ummm some where...lol...ill look around for them
Did you get a good price on the Vibrant stuff? I carry it if you want to check prices with me sometime.
What's the deal with the two 02 sensors in hurley's downpipe?
-Doc
the 7afe has 2 stock O2 sensors
my dad said he would make me a sports exhaust for my car (hes made lots for his race bikes and such) so if he can weld all the piping and stuff what parts would I need to buy? i've also heard that I could use 3s-ge headers on my 5S-FE is this correct?
also because my car is a daily driver and I cant really take it off the road does anyone have "plans" or something like that of the exhaust for our cars? if it matters mine is a ST204
Here is, like promise!
4-2-1 Header with DEI wrap.
OBX SP2
i will put soon some videos...
now that we are talking about exhaust. can somebody teach me the parts of the celi.
now, i know the first part is the catalizer that goes into the downpipe that connects to the flex pipe, but i see my car has like another cat and a tube before the muffler? what are those.
the smaller one is the cat, the bigger muffler looking one is the resonator.
ok so it flows like this.
header -> Cat-> downpipe----> flexpipe---------> 2nd cat------------Resonator----------->muffler!!!
thanks. too complicated!!!
i dunno i have 2 cats...maybe its a obd thing??? i dunno just guessing...maybe dr tweak could straighten us out
i tought 97 gt have a cat in the header, thus 2
I beg to differ on a number of points, but what I have to say doesn't apply to the US folks as they don't have 3s-ge motors and legally require catalytic converters....
But assuming you have a 3S-GE motor as I do, Which comes with decent 4-2-1 headers and a 2.5" system as standard and you live in a country with no emissions laws as I do....
1. The point made about a cannon muffler on a stock system will do nothing at all except sound louder...
-- the standard 2.5" is already big enough for a 2 litre NA motor, still need to upgrade pipe?
-- the cannon muffler flows straight, it doesn't zig-zag from 1 side to the other in an oval
-- the stainless steel cannon muffler has got to weigh less than the large cast iron oem muffler right?
2. the point made about not decatting...
-- the uk 3s-ge guys say their midrange acceleration is freed up
-- a straight pipe weighs 15kgs less than the catalytic converter
For those of us for whom a cat is required, there's always the option of investing in a good quality high-flow cat if you really want to free up that airflow. I think ceramic cats are supposed to be the best, but they don't come cheap.
A $100 magnaflow hiflow does the trick for almost nothing and very little restriction - IMO the way to go.
I've been driving my car with a straight exhaust, no cat, for about a month now and the P0420 Cat Below Efficiency code only came on once about two or three weeks into it. I thought it would realize there was no cat much much sooner and more often. I'm waiting for it to come on again to determine the approximate time frame and driving habits that cause it to throw the code.
My backup plan if it threw the code too much was to use some spark plug non-foulers from Autozone and do what some Subaru guys do to pull the O2 sensor out of the direct stream of the exhaust gas which causes it to read leaner than the primary O2 and tricking the computer into thinking everything is fine:
Oh that is an awesome idea. Will defintely help the OBD2 guys when they install a header.
Out of curiosity why would you want the o2 sensor reading leaner than it is? When the ECU reports cat below efficiency how does this impact the performance and driveability of the car?
For this trick to work would you not need a separate AFR management system with a separate wideband o2 sensor?
The second o2 sensor after the cat does nothing but tell the computer that the cat is working. The converter is supposed to filter out the exhaust gas, so a leaner reading means less fuel in the mixture with means the exhaust gas is being filtered well enough. The second o2 sensor does not affect how the car runs.
What I did on my WRX (and I know this has no practical use in the Celica world unless turbo) but I had a small curved pipe welded into my downpipe for the o2 sensor. This way it sits out of the stream, but still reads normally. Let me try and dig up a picture.
Hey!
Whats best option ?
1x 18" resonator
or
2x 10" resonator ?
or
other configuration ??
hey everyone
figured i'd show ya my muffler. i have a custom catback..but had to get a new muffler welded on and it actually just got done about an hour ago. This time i went with the OBX B10 that they were talking about in the beginning of this thread. I definitely like it, its pretty big, and made it A LOT quieter than my other muffler. heres a couple quick pics. sry if the quality isnt that great its from my iphone
lemme know what you think about it
Thats a BIG muth*f**er muffler!!! ehehe
Nice work, but I personally don't like how many people have their mufflers pointing down, like you do. I prefer the look my Supra had, which was actually tilted up and angled out.
Basically it's this:
Compared to this:
You decide which one looks better.
-Matt
yeah i wanted it to have more of an upward tilt..but the guy couldnt mess w/the piping w/o charging me..it doesnt look horrible tho..i can deal w/it..plus they are both diff cars and have diff looks..if my piping were any lower it would scrape all the time..my muffler already scrapes
and yeah..its freakin gigantic..didnt think it'd be that big lol
Sounds nice. If you stumble around a video camera take a vid for us!
-Matt
mine is just the stock exhaust with no muffler. cut off at the rear axel. sounds good too.
Whats the standard piping of the 7AFE engine? I am planning to buy the Megan Racing N1 muffler, but need to make sure it fits. Is 4" outlet overkill?
I believe the smallest they have is 2.5" inlet (the muffler). You will need to go to an exhaust shop to have them make a piping adapter, since I imagine the stock piping size is 2" or smaller.
does anyone know what difference to the sound of a stock exhaust and muffler these three mufflers would make?

would these sort of sound like a cannon/fart can/canister? I kind of like that sound but like the look of these better. or if these would sound like it actually goes fast that would be cool. which one would be the best? although i am looking at the OBX coz they are cheaper haha
EVO. I know how it sounds, and it is good.
I personally like the OBX WS. I didn't know they made those, it looks nice. I'd rather get that then a canister.
can you describe the sound they make? i kinda want it to sound like a fast race car or deeper. If you saw the dual exhaust set up video in the for sale section wud any of these make it sound close to that? but i like all 3 of these :S
PS i know my car will only be stock but i want it to sound cool
Got my exhaust off ebay for $30 shipped. Tried it out after hearing a nice one on youtube. I must say, it sounds great the way it is, without the silencer. I get a lil pop when I switch gears after 1st and 2nd, but I kinda like that. Reminds me of rally cars. Anyways, I went with 2.5" piping and didn't feel any HP difference....... Until the inside blackened out and the burnt smell that was coming out of the exhaust left. Now I feel a difference. I know nothing of HP differences, but if I had to say, this feels like I gained around 10HP from it. But the car does get up a lot faster. I know my baby to the point where I can tell if pressure in my tires is lost from how she handles and accelerates. So yes, there was a HP difference. I wanted to get an HKS, but I will wait until after the swap in late 2009/early 2010, where I will go with either 3" or 3.5" piping.
I just got my new JDM 7afe today, put in monday ! Oil pan cracked, slung a rod in the original (152,000) I have had the car since late august. Early sept. clutch had went out. Had stock clutch, and the man who i bought it froms wife had been driving it. She hit a parked car... WTF?!? Fender is got a small dent in it. Anyways to the point, I go to the local Pull A Part, i just go and look around often and scope for cars i'd like to buy and have a nice lil project this summer. While walking around with a friend i found a Honda Crx, ( Had Civic cut out in the hood LMAO). The car looked like crap. Anyways, while laughing at this, i glanced down and saw a Dynomax exhaust on it. Looked it up its a muffler Dynomax and Bosal got together on. Sounds really good. Wasnt too hard to find it on youtube. I'm going to go 2.25 piping, and delete the cat.
My question is
What would i do with the O2 sensors?
BTW ... 1994 St 5 speed.
My friend also had a 1994 St Auto, he cut his cat and resonator off. SOUNDED LIKE ****. His muffler was pretty cheap, and sounded crappy. He put his resonator back on, didn't sound THAT bad, still sounded like a ricer b/c of that muffler.
Yes yes, In mississippi Not having a Cat is illegal, BUT people here really don't care as long as your not doing a drive-by.
My two cents.
I agree with the anything above 2.5 pipe on a N/A, anything bigger, sound like a ricer who's about to blow the engine. I also know in most southern states a resonator isn't required, running pipe no bigger than 2.5 with factory resonator to a decent muffler to me and many others not so raspy. The resonator muffles the sound, but not all of the sound. It helps the sound volume and the sound quality. To each their own, but different people think different systems sound like complete ****. I have a friend who has a magnaflow cat, older Greddy muffler 2.25 pipe, it sounds like crap, but so does a straight pipe with no cat or res. to a muffler, its way loud. If people can hear you over a mile away in a city than yes, its way to loud.
st id say 2.25 or 2.5, and just got to your local shop and have them weld a new bung in a location similar to then og one. so it doesnt mess with the sensors positioning and stuff like that since it all programed for the way it is so it may mess with it if you move it to far from the original position. but i may be wrong
is this the obx you were talking about?
I want a deep sound, not something high pitched and rattles.
no mine is a decent medium tone not too rice'ish but im thinking about putting another resonator to deepen it a little more
Akirad, you running a stock resonator?
runnin drums or did you have the disc upgrade? Im hoping when I do get the chance to upgrade the exhaust I'll be running a cat back set up. New parts all around!
Wish I could give you one. Im trying to run magnaflow all the way. We'll see how that sounds in about a month (i hope)
Yeah, hopefully i get the set up for x mas, I doubt it though. Not a bad price through hot exhaust w/ military discount.
I know. I think the total price comes close to 130, thats street series muffler w/ new resonator plus the free shipping. Save close to 40 duckets.
ah g.i discount, i miss that. went with my sis al the time when my brother-in-law was in iraq. Yea, i want that deeep tone too, i was thinkin maybe stock resonator with magnaflow cat, i don't mind the pop when revvinig down, well i do mind on honda's sounds like someone who has bad gas.
oh yea, anyone know the difference between the obx b9 and obx b10?
for all of you using the cat backs like the sp2, etc. It doesnt hit the axle or anything? My over axle bend(custom) is actually hitting the bottom of the frame and it just vibrates on it and annoys the hell out of me. I was thinking about getting this but i'm not 100% positive yet
So back a while ago i got a cat back magnaflow exhuast and i still had my original headers with the 1st catalytic converter and then the original 2nd catalytic converter. It sounded really nice a had that deep sound sorta like a subaru. Really loved it. But once i got aftermarket headers installed and magnaflow high flow catalytic converter, the tone changed a bit but i still liked it. From 4-5,000 rpms in 1st and 2nd gear only i get a raspy noise which really sounds horrible. If i were to install a magnaflow resonator would it eliminate the raspyness noise and keep the same great tone that the exhaust produces right now???
Hello!
I have a Celica ST with the 7AFE engine and stock exhaust. I want to tune it up, and I know a exhaust shop that can do the job for me. I am looking for a exhaust which sounds great, but not too loud. I was thinking about the "Megan Racing N1". What is recommended for my wish?
Is it just to take of the old muffler, and plug this on? Or do I need some more, like a resonator?
Well, if you really want to do it right you want to do a cat back. get larger diameter piping from cat to the muffler. You may want to get a new resonator that matches the piping diameter though...better flow. 2.25 should do you just fine.
alright then i'll think about getting a resonator. they charging me $110 installed which is good. Would it be ideal to do straight piping or leave it as is and let the piping go over the chassis like it is right now.
I would recommend not doing straight pipe.. I did a 2.5 Straight pipe over axel and I'm about to put a piece of dinomite in my car and walk away. It's ridiculously raspy and annoyingly loud. I'm buying a resonator in the next week I hope and I PRAY that it helps w the raspy crap! Idk if maybe i also bought a faulty muffler, something busted loose in it or something and that makes the rattler worse, IDk but its obnoxious. I would advise not to do a straight pipe w/o a resonator or something.
It won't be bad was a resonator added, but what muffler you have also plays a key role in how loud it is.
Ehehe
Oh yeah! I having the same problem....
I waiting the arrive of not one but TWO resonators...
I choose this ones:
I hope this low down the rasp and volume.
hmm... Where did you get that from? does anyone know any GOOD brands of resonators?? I was going to get one off of summitracing.com but if there is a GOOD brand? I thought borla was supposed to be good but now I'm thinking about replacing my muffler too
Borla is supposed to be decent. But if your not running a resonator its going to sound like ass. When I was getting quotes around here one guy said that I didnt need one, strongly recomended that I didnt have to get one. I left and went somewhere else. Found a good place, The guy knows exactly what I want and recommends a resonator. I figure hes pretty good, there is a PT club here tht takes their exhaust stuff to him. Seems honest too, unlike the other one (told me he could have it up and running in 1/2 hour max....dont know if i trust my stuff to be done that quick.)
Yeah, I just bought 2 of the same resonators that were posted above. I went through a few forums and it was recommended that 2 would sound best. So I'm going to get those thrown on ASAP and hope for a significant change. and you're right ^ it does sound like a$$
From here: www.aeroexhaust.com/
Now my doubt is ...
Whats is the correct way to install 2 resonators ??
One near other? ...leave some good space between ?
I found another site that sells um for cheaper and w free shipping. and I Imagine I'll leave space but I'll let my exhaust guy do his thing I'm sure he knows what would be best
Thinking of getting a 3" piping, magnaflow hi-flow cat, vibrant 18" super quiet resonator, and probably magnaflow muffler....think this will be a good setup for the 3s-gte?
Sounds perfect, that's very similar to the exact setup that I run on all of my 3S Celicas, and they sound AWESOME.
-Doc
alright so I bought a couple of the ar25 aero resonators and then after realized they're on backorder. can someone recommend me a good brand or resonator to buy, I HAVE to get something done FAST!!!
OWWWWWWW!!
I get my 2x aero 20 resonator today!!
I went to my local shop to solder them in!
1 hour work...
And result is!!!....:
THIS WAS NIGHT TO DAY CHANGE.....
Perfect deep bass sound.. Looks very like OEM Sound in low RPM.
But you get in 3.5K RPM...You can hear a deep cool bass sound..
PERFECTT!!!
Now i can enjoy calm weekend drives with my girl in highway and later in day go with some buddys to RACELAND
^Diddo!!! I just got mine done yesterday and OMG complete difference.. I can hear myself think in my car once again! I can actually think in my car once again!! And highway drives are torturous anymore! But has a great deep bass sound still! My car doesn't sound like a cheapo ricer anymore ha!
BTW how much did it cost you to get them welded on to your exhaust??
Just wondering if anyone can help me out... I just dropped headers into my 5sf but I had to take my cat out... Is there any way that my cat can bolt back on while my headers stay in? My car sounds a little riced right now. Or should I just scoop an Apexi N1 universal muffler and run some 2.5" piping and leave the cat out?
Since you have a 5s the cat is pieced together with the factory manifold. And the header you bought obviously comes without. If all youve got is a header and factory exhaust I really can't imagine how the exhaust can sound rice. If you add a muffler and piping with no res and cat your going to sound even riceier. Now I am running a 3" DP 3" exhaust all the way back and its pretty loud, but I have that loud grumble. Lets say I were to add a resonator the car would sound amazing.
i have also heard that the ebay header with stock exhaust will sound a bit ricey...
a couple quick questions for you guys,
do all 6gc's with the 5sfe have 2 cats, or just the cali-spec ones?
does the surewin (ebay) header for the 5sfe replace both cats or just one?
only california 6gc's have 2 cat converters. The main converter is located right inside of the headers. and 2nd cat converter is under the car obviously
all celi's have 2 cats. at least mine did i'm on obviously not from cali. One in the header and one on the exhaust, and the ebay header removes the first cat since you are removing the stock manifold. And yeah with a stock exhaust it does sound a lil ricey..
Just wondering how this sounds to you guys..... Went to a local 'exhaust center' as they call it and the guy priced me at around $350 not including muffler for 2.5" piping, "high-flow" performance cat and a resonator... I noticed in the first post you mentioned paying a little over $100 for your set up on your supra, I'm trying to figure out why mine will cost 350 lol
resonators aren't all too cheap but I got my exhaust done for 110. But I bought a muffler before i went to get it done and that wasn't very cheap either.. Idk, maybe its just me but that seems kind of high, maybe I'm just lucky to have an inexpensive exhaust specialist near me..
I feel like I'm not contributing at all to this thread but I'm sorry, I just wanna make sure I make the right choice haha... But anyways, went to another shop and I think I might go with this one, priced me at $90 for 'pipework', $150 for the flowmaster cat converter, and $50 for a resonator... $290 total so you don't have to bust out the TI83.... Still feels like I'm getting ripped off but oh well...
Any one with sound clips? I'm looking at a setup with an ebay header, then probably 2 or 2.5" piping thru 1 or 2 resonators to no muffler. I have experience with v8's using a resonator and no muffler and getting great results, but not sure how it would sound to have just the cat, resonator, and straight back.
there is a sound clip of mine but i have a st with the stock exhaust and a muffler sounds decent to me, but i wanna re-do it
Does this one belong to anyone here?
http://www.youtube.com/watch?v=Asig7LdaqI4
It sounds so good! Pretty much exactly what I'm looking for if I go with a muffler, and I'm definitely going to use the 350Z/G35 resonator (especially since my buddy might be doing exhaust on his G35 soon, free parts for me )
I'm a ricer so I got my muffler welding on to stock piping.
Not wasting money on a exhaust system that won't help much haha.
The whole thing will come when the 3sgte is bought.
I don't know why I haven't posted this up yet...
This was the exhaust system I had installed on the Yelli Celi. 2.5" under-axle to a Vibrant Performance muffler. Sounded great, but that might have been the 20V.
http://s22.photobucket.com/albums/b342/BeMineForeverBRH/?action=view¤t=d672d7f5.flv
^ That looks like a great setup. What'd that run you if you don't mind my asking? I've got a muffler set aside already, (IDK exactly what kind it is, it actually looks very similar to what you've got there) but the piping you've got there looks like what's probably the best choice.
it was actually free, but only because i had paid for the system, and the shop did a bad job on it, so i brought it back and told them to fix it, which ended up getting an entire catback fabricated again. that setup initially cost me around $330 dollars for parts and labor. since i didnt want them welding straight to the muffler i got two giant hose clamps (the ones you tighten with a flathead) and they fabricated the mounting bracket on that.
sorry for the lack of proper punctuation. i'm on my cell phone right now.
A pro wielder will actually use an exhaust clamp that was made for your round cannons. vs wielding on the muffler to hang it up which will eventually lead to rust and a hole in your muffler. Straight pipes do not count for a muffler unless you want to go deaf.
I havent heard to many people talking about the difference on GTs. I got a 94 gt and thinking of going with the obx b10 with a aero resonator from the cat. 2.5"
Is there any difference between 2.5" and 2.0"?
Right now on my 92 I have an ebay header(which deleted my cat) and stock piping from there back to a "noir style" muffler, which is black, has a 2.5" inlet, and a 3 inch tip. I like it because it has a nice deep tone, with a stock look.
I have a nice little exhaust leak near my flex pipe, so I think once I fix that, it will sound really good, and I will get a sound clip for you guys.
i finally got time to get around to this. im gettin 2.25 piping with a 12''magnaflow resonator (should be here tomorrow) to a dynomax muffler.
my question is cat or no cat?
i want that kind of deep tone not raspy.
If any of you would please give me some advice on this because it is either going to the shoop tomorrow or monday.
id go for a high flow cat
that isn't am option to me at this point I want to eventually. but for right now no cat or leave the cat? sorry for spelling I'm on my phone
well do you have to worry about emessions, if not dont wory but if you do cat is a must
any idea how much louder and what effect it'd have on the sound?
well the set up i had when i got my headers installed was i took out the old cat and went straight pipe. And lemme tell you, sounded like crap. Then put magnaflow high flow cat and sounded nice. Now its still a little raspy but only in 1st and 2nd gear after 4k. So once i get magnaflow resonator (or if its even called a resonator from what another member said) it will be a perfect set up i think.
I called muffler shop and they told me to choose between a 18 inch or a 14 inch resonator. is there a 12" magnaflow resonator??
but wow man those magnaflow cats work wonders and I'm going to get one in the future
sure is a 12 inch. I ordered it from ace's the same guy who put flowmasters on my old mustang but see I'm going same pipe route as factory and i.ll have stock header magnaflow resonator and muffler.
it maw have been 14 if maw have just gotten confused
if you have stock headers, leave the post cat on (the one under the car) and it should sound good
the cat by the bottom of the header or the second one and where should the magnaflow resonator be mounted at
Since i live in CA, emission laws are very strice over here obviously cause population of CA is so big.
The pre cat (other wise known as the cat converter that is inside of your stock headers) and then theres the post cat (the one that sits under your car.
When i installed ebay headers i obviously took out stock headers, which then in turn took out the main cat converter. (so next time i go to do smog i wont pass).
Your doing a cat back exhaust system, so that means you can either take out the post cat (one under your car, which i advise not to take out, but ask exhuast shop to see what their opinion is.)
The resonator goes right before your dynomax muffler.
get some pics of your car on your profile!!
thanks man oh how close to the muffler? and I just got another camera ha no idea where my other one went. I ask how close because if I don't like the muffler I'm gettin an obx
oh if the pre cat is connected to the header how difficult is it to remove
and if I get a magnaflow cat? could ya give me a run of what I need? and for right now would I run 2.25 pipe from header to post cat
I'm not too sure you'd want to remove the "pre-cat", with all the work that would be involved manufacturing some new pipes and installing, it might be cheaper to get the ebay headers. The easiest thing would be to run the cat back (which is from the "post" cat and back). Its simple, run 2.25-2.5 pipes (mandrel bent pref), from your post cat (which you can either replace with an OEM, Aftermarket, or High Flow...or just remove, that would depend on your emission regs from your state), to your resonator (again, can replace) then to your muffler.
The main reason why I recommend you dont mess with the pre cat is if you do decide to remove it, and take it to a shop, they may not help you out as your tampering with emissions stuff. But if you know someone who can do it and your dead set on doing it, go for it.
just use the edit button if you want to add to your comment, i guess ur not supposed to post up on the same topic two times in a day.
alright sounds good. i have to get a vid of my set up on this. I'll record the exhaust sound with the camera pointing at my exhaust, and then a drive by from 1st through 3rd. except 3rd tops out at 85mph (speed limit on freeway is 65mph and i wont be filming on the freeway). So some of the members that are in charge of closing posts and warn people of misusing the forums, will tell me that we dont want to advertise any sorta racing. so i'll get permission to see if doing a drive by until the end of 3rd gear is ok.
thanks. i.ll run from the post back for now. I despise exhaust that's way too loud and raspy and I don't want mine like that. i.ll put a clip of it up when it's done
I finally got my exhaust on. got pictures before and after and a video i.ll post up later. have stock header pre cat post cat magnaflow 12 inch resonator to dynomax muffler not that love though but it does have a deep tone. would a high flow cat fix this? it gets raspy around 4800 rpm's but that's find I don't usually ldu it get that high
^^^^ Scratch that here are pictures
Well its been a long time coming but I'm finally getting my exhaust clip up here hopefully it does my exhaust justice, I've only been able to hear it on my camera ha ha
Custom 2.5" exhaust, header back, 2 AR25 AeroTurbine Resonators, and a Borla XR1 Muffler
http://s304.photobucket.com/albums/nn185/bseaman_5/?action=view¤t=MOV00118.flv
Do i need a resonator with the Megan Racing N1 muffler?
And, is it a good muffler?
I am planning just to change my stock muffler with a new muffler which makes a bit more tasty sound. I have no plans to do a full cat back yet, so my plan is to try a muffler before I am doing more changes. I have a stock ST, so I think the size of the exhaust pipes is around 1,75"?
my personal opinion man get the muddle and save with two acts and that factory denser it won't be that loud I got my piping done for 60 even and got the muffler for like 12 bucks at pull a part. and 31 bucks for the resonator
ilike header back 2.5, no cat ,one maybe two res.,to the muffler and it should sound good
here just a short clip of my exhaust sounds. ill get a better vid once i get clutch and gasket installed in about 3 weeks
http://s483.photobucket.com/albums/rr197/BonzaiCelica/?action=view¤t=Exhuastwithtorngasket.flv
Finally got them in! Magnaflow resonator and street series muffler! Cant wait to get them installed, hopefully thursday!
that looks beautiful
Just wait to hear how it sounds.
I know this is gonna sound motarded, I should really run under axle, right?
if the exhaust shop can do it run it like stock but if not under is fine too and less bends in the exhaust
Hey looks nice! I just got my Aero Turbine 2540i muffler and AR25 resonator a few days ago and my 2.5" stainless pipe just got delivered today. Man I cannot wait to get this put together - unfortunately my cashflow has been dwindled down by repairs to my other 3 vehicles so it will probably be a few weeks before I can get it installed. I'll take some pics in and try to have posted in a couple days of the stuff - looks beautiful. One question though - how critical is it to have the stainless pipe mandrel bent? I've called every exhaust shop around within 50 miles of where I live and no one does mandrel bending - I couldn't believe it. Will it affect the performance or sound? Also my original exhaust design was to have all pieces bolted together using flanges (the downpipe, resonator pipe, and muffler pipe all separate pieces with flanges) so at anytime I could unbolt a section and replace it without having to cut and weld. Is this a good design or would I be better off just having it all welded together as a "one piece" system from the downpipe back? Thanks for the input and again those are some nice pics - I always did like Magnaflow.
I am going to have my exhaust done in a couple weeks at the most. It isnt going to be anything super special, but it will give it a nice tone, and still help power a bit. I have a 4-2-1 header on its way, which will get rid of the first cat, and I have a muffler for it. I am leaving the 2nd cat and resonator as well. I dont want it to be overly loud, but I do want a little bit of a tone.
I will post pictures and a video when I get everything.
Finally got it on. OK ,sounds good, except for that damn exhaust leak bu the flex pipe is allowing the gasses to escape before it can hit the muffler. Im sure once I get that fixed It'll sound real good. Right now though it has that real deep tone, I like it.
hey spider 77 how long is that magnaflow resonator???
Yeah, its nice. Its still hard to judge how nice cause I have yet to get my exhaust leak (rusted flange on the flex pipe) and most of it is shooting out before it hits the cat back. Although currently it has a smooth deep tone, just not as loud as some people like it. I had one guy in his civic tell me that he didnt like it cause it wasnt loud, then he drove off in his weedwacker.
i just recently got my custom exhaust done. 2.25" piping WITH NO CAT. yeah i said it, no cat. And a MagnaFlow race series muffler. and it sounds wonderful. it has a very nice deep tone and a slight ricey crackle. sounds different from any other cars around here so i'm very happy with it. i'm waiting on my header right now, should be in this week hopefully.
oh so you have original header right. ya no wonder why it sounds good. Once you install the new header that you bought it will sound ricey gauranteed. You better get a high flow cat and then maybe a resonator depending on how your exhaust sounds.

Pics and clips to follow.
Hows that hi flow cat working for you?
umm.... it flows. I think that the engine is "breathing" much better now. but its kinda hard to tell just how much by the butt dyno. I find myself just listening to my exhaust sound instead of paying attention to my rpm's and speeds. But I have no idea how much the hi-flow cat helps.
When I pull up to a stop light and I hear my exhaust, I start to look around for which car its coming from. then I laugh at myself because, duh, its my car.
Edit:
Here's the pics from the exhaust shop. They did a good job running the ehaust over the axle.

Since I sourced the components myself, I picked the magnaflow muffler without the tip on the end. so they tucked the muffler up inside a little bit and poked the exhaust tip out the back a little bit.

Ok, so I finally got that pesky exhaust leak fixed. Got a new front pipe to replace the old rusted one. Finally got around to slapping a vid on here. Its done on my cell phone, so its not the greatest quality.
Its a magnaflow resonator and street series muffler, running 2.25 piping. The next thing I want to get done as far as exhaust goes is get a header and high flow cat.
cant this be stickied, it took me a while to find.
Which resonator can i use with the OBX sp
does anyone have an recommendations on a highflow cat?
i just recently bought new headers on ebay.
http://cgi.ebay.com/ebaymotors/Toyota-Celica-90-97-GT-5SFE-2-2L-Stainless-Steel-Header_W0QQcmdZViewItemQQhashZitem53dcf2f4d7QQitemZ360189195479QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
im wondering how much more hp would this add on my 2.2L 5sfe?
im about to get a 2.5" piping custom catback as well and was wondering how much hp this would add combined with the headers?
2-3 hp, maybe
We don't have Hondas. We can't slap on an exhaust and get a billion hp.
No, 2-3 for the header+2.5" catback.
Welcome to the non-existent power modifications!
you kids...
Go put your stock exhaust manifold back on and do a few dyno runs, then put the aftermarket header on and run a few more. You'll have a couple HP increase. An exhaust isn't going to do much of anything except make you louder. Unless you've got a dyno sheet saying you got super mad jdm tyte power gains then you're butt dyno holds no ground here.
is it okay for a 5sfe to go beyond 2.5"? perhaps 2.75"? or something..
Unless you're going to eventually turbo it, I would stay at 2.5". The larger you go the more low end torque you'll sacrifice.
Should I put after cat first resonator and after that middle silencer or silencer first and after that resonator? Does it make any difference?
You don't need to run a Y pipe. Don't listen to him.
Two mufflers is VERY common. It decreases sound without much of a decrease in performance. Run them like this - Cat - Resonator - Muffler - Muffler
Edit: If you run an ultra quiet resonator then there is no need for a second muffler, as thas is basically what Vibrant's ultra quiet resonator is.
You stated:
"If you had a y pipe then that would come after the cat, and split in two, so you would need two resonators and mufflers. " No, that is what I said. I never said that two mufflers requires a y pipe, It says that if you have a y pipe then it requires two mufflers, etc....
I would like to see some pics of a multiple muffler set up running on one pipe. Of all the time Ive been messing with cars, Ive never seen that. The only time Ive seen more than one muffler is on a true duel, y pipe, x pipe...etc...
Temp, if your worried about noise levels, then drop some money on decent stuff. I know my set up is posted on this thread, and its not "lawnmower" loud. Its nice and deep and the only time it gets loud is when I smash it.
The keyword is that you implied it.
Two inline mufflers
OK, first, for me, thats the first ive seen two mufflers run in series. So no resonator, muffler instead? Cant tell from the pic.
And secondly, I didnt imply anything, as I directly stated it. Had I said, your running two mufflers, your going to need a y pipe. Thats implying it.
Actually, that would be stating it. You're stating he needs a y-pipe.
Ok...this is getting real stupid now. I said if he were to run a y pipe, he need two mufflers. Not that if he had two mufflers he'd need a y pipe. As it is, this is getting way off the subject. Temp, you pretty much want a low exhaust without affecting performance, correct? Do what you feel is right, you want to run two mufflers, go for it. I think that you can get away with running the vibrant resonator (the ultra quiet one) and a muffler, then call it a day. Don't know much about that resonator because I don't have one, but someone on here has to have it.
I am due an exhaust replacement like last year.
Anyway, I have a Magnaflow cat due in soon. I also wano want an OBX tailpipe. What I was hoping for was to go under axle as opposed to over axle. I have a 7afte.
What are the implications of under axle.
Thanks.
J
If you're going to go under axle then you need to make sure that the exhaust shop fabricates the piping when your car is on the ground. This way they get the most ground clearance.

Does anyone have pics of the under axle system?
some pics of the header back exhaust i made for batman722 and hurley97's beams swap.

is an hks high power silent exhaust system better performance and air flow characteristics than my current magnaflow exhaust. I have the magnaflow exhaust that looks like an oem style exhaust.
Im asking if the hks has better performance over my current magnaflow exhaust becuase the hks is a canister and seems allows the exhaust to breathe more freely? Anybody know the answer
so can anybody answer my question ^
also I was looking at buying a decibal meter and seeing just how loud my exhaust is all the way up to 4,000 rpm and then returning it. So maybe we could get a list of different exhausts and see just how loud they are!
I have a 4-2-1 header,with 2.25" piping with one cat and a off brand muffler...gives it a great rumble at idle,but ricer whine above 3500 ona heavy load
hey presure2 can you get an exhaust clip of that exhaust. I know that the 3sge beams redtop comes standard with 2.25" piping. I was looking at exhausts here on the nengun auctions and on the parts database and it seems as though the hks hi power silent exhaust system is the only one that has 2.5" piping. Are there any other exhaust systems that have 2.5" piping?
I mean what kind of difference in performance would there be in a apex n1 evo exhaust with 2.36" piping vs an hks hi power silent exhaust with 2.55" piping?
anyone??!
I'm guessing that nobody can give you a definite answer, so nobody is wanting to guess at it and spread misinformation.
Generic resonator vs vibrant resonators?? I know the saying goes, "you get what you pay for".. but does it apply with resonators??
EDIT: Yes I searched, AND I just read all 13 pages
K.. i would really like some advice. I'm getting new exhaust. I was planning on getting vibrant ultra quiet resonator, with a magnaflow muffler. 2.25 all the way since its just an ST.
Now, the shop is trying to charge me 100 bucks for a magnaflow resonator, and 100 for the muffler.
Online i can get the Vibrant ultra quite resonator for a 100 dollars, & magnaflow muffler for 50.
What if i just put 2 magnaflow mufflers? will that work almost as well as 1 muffler, 1 resonator?
or bite the bullet and spend 100 bucks on the resonator... please please any advice will be awesome..
thanks for your time.
can anybody answer my question??
can anybody answer it now? how about now?
I'd email C-one and ask them for clarification on the dB levels and how they came up with that reading.
http://www.gcaudio.com/resources/howtos/loudness.html
this will give you an idea on dB levels
The performance question is probably not going to be answered for sure because I doubt that someone will dyno their otherwise stock car, then change from 2.25 to 2.5 exhaust and dyno again.
you think c-one will be able to answer my question?? Its a japenese website. I mean im sure somebody speaks enlgish or they can translate it on the comp.
I think I just might ask hks as well as to why they chose 65mm piping over 60mm like every other exhaust company decided to choose? Hm but being that C-One only creates toyota parts for the celica, I would assume that they would know a little bit more about the 3sge beams redtop. But I'll write both hks and c-one an email.
here in NZ our limit is 95db, though if your vehicle came out standard/factory with a louder exhaust then its ok
http://www.howstuffworks.com/question124.htm
so i have a 94 gt, and i wanna get a header for it and ppl say its going to sound like crap without the cat, but sence the cat is right off the manafold, and the new header is going to get rid of that is it worth it or is it going to sound like crap?
Well you may hear different opinions but I don't think it will sound bad at all. That's exactly what I did when I got my '94 GT coupe over 2 years ago. Here's the link to my Photobucket album with a couple of video clips of how my car sounded then http://s591.photobucket.com/albums/ss359/bdawgbp1/94%20Celica%20GT%20Exhaust%20Clip/ . When I took these clips all I had done to the car was a 4-1 stainless steel race header and cold air induction. The rest of the exhaust was all the stock exhaust that had never been touched. You are also right that when you install the header it does away with the cat - as long as you have a Fed/Canada car. The Cali cars also have a cat under the car. When I get some time I'll post some new vids with my new exhaust that I had installed last month (full 2.5 inch stainless from the header back with Aero Turbine resonator and muffler. It also has an electric cutout just past the downpipe for the "drag-car" sound and power at the push of a switch or button. To answer your question - yes, it's worth it.
i have headers and a cannon on my car, its not raspy at all, it sounds great actually
Found a header for the 7a-fe on ebay:
http://cgi.ebay.com/ebaymotors/1994-1995-1996-TOYOTA-CELICA-7A-FE-ST-EXHAUST-HEADER-_W0QQcmdZViewItemQQhashZitem27adc0b654QQitemZ170418812500QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
This looked good, and cheap right?
Is this bolt on, like the seller says?
it is about 3 inches short and you will have to have a shop make it fit right
Okay, thanks! How do you know? The seller says that: "Direct Bolt-on Installation, Require NO modification". But, everybody lies...!
soon to have pics up of my exhaust - dual side exhaust with dual tips coming out of my boomer skirts
What would you think about this system:
- free flow cat (don't know yet what...)
- Aero AR25 resonator
http://www.aeroexhaust.com/index.php/resonators/sedan-resonators/ar25-2-5-inch-vehicle-resonator.html
- Aero 194 muffler
http://www.aeroexhaust.com/index.php/mufflers/sport-import-exhaust/194-small-tank.html
- Some tip for muffler
What would you think, do I need ear plugs?
Does anyone have this Aero resonator and Aero muffler configuration?
i have a resonator straight pipe to a aeroturbine muffler but its the cannon tipe i like the way they sound but mines wayyyyyy loud
Thought i posted in here, but i guess not.
Well....after riding around with an open down-pipe for a year, i figured it was time to put the exhaust together, weld it up, and hang it.
Heres the set-up that i have
Full 3" turbo back exhaust consists of the DP, to a 45* bend and up and over the crossmember to the flex pipe, from there it flows into the QTP electric cut-out i put in. From there its basically a straight pipe all the way back to a 3" Megan muffler.
with the cut-out open it sounds awesome, super throaty and a little more quiet then an open downpipe.
When the cut out is closed the car is almost silent. The meagn muffler does a great job of muffeling the noise, however i wish it was a little more deep, and had some more sound to it.
i love the way its set-up, but it does have a couple flaws. For 1, its pretty low, since i ran it under axle. When my buddy welded it up, we were somewhat in a rush to get out of the shop, and i just wanted it on, so instead of throwing 2 extra bends in the exhaust and staying in that "stock tunnel" we went right under the gas tank and out the back. We bent the sheild up against the gas tank to deflect some of the heat. Other then that is perfect, and im very happy with it.
this is the 45 that bolts to the DP into the flex and cut-out section
And what it looks like on the car...i'll have to get some under-body shots, but you get the idea
Is a glasspack considered a resonator though?
Ok lets say for instance I go with an all out stainless steel header, stainless steel front exhaust pipe and cat back exhaust system with everything stainless steel except my original magnaflow exhaust. Will that change the exhaust note of my car becuase of my whole exhaust system being stainless steel, will it have a high decibal reading???
anybody want to reply do my post ^.
also are all aftermarket catalytic converters stainless steel???
oh griffgirl, speaking of decibals, I mentioned a while back ago about buying a decibal reader and measuring the loudness of our exhausts to see how loud they are? and then posting them up with different exhaust setups and so forth! but no one will do it
http://www.3aracing.com/pdut_detail.asp?ID=129
i picked up that muffler from autozone one day because i needed a flesh pipe and saw that on the shelf for a decent price. like $50 i think in the store. figured i would give it a shot. i figured for the price it would sound like a pissed off bumble bee. to my amazement when they took it off the rack and started her up i heard a nice, clean, and deep tone. i've thought about removing some of the exhaust like the cat and running larger piping. but i'm on the hunt for a gt shell to start the 3sgte swap. toyota has under there but i really don't think i need to. that w/ a CAI i get better response and clean deep exhaust from low rpms all the way to 7k. will make a sound vid and post if anyone is interested.
kinda interested in a dual pipe setup one each side any one done it and how was it done been trying to nut it out for a lil while now
Look up the user kaos.
Is he the only one who has done a dual exhaust?
The only one I've seen on 6GC.
Fwiw; I went to a single exhaust after my headers were installed.
Here's a link to the last few pics I had of the dual exhaust: https://picasaweb.google.com/jdwinterton/NewExhaustMay09?authkey=Gv1sRgCK_wxN7-zv-PZw&feat=directlink
totally gunna miss the duals
thanks for that givin me some ideas on how i wanna go about it
Alright, kind of resurrecting this, but I have a few questions that I haven't seen answers to after going through this thread.
First off, how much HP does one realistically stand to gain from installing a catback setup? Does that change if the cat is included in the upgrade? Or is this more a simple issue of finding the right sound?
I have a 7a, and I'm thinking about doing a straight-pipe 2.25" setup from the cat back without a resonator. With a good muffler, will I notice any performance increase?
It's a very small increase at that. I went from stock to after market header and down pipe, deleted cat and 2.25 piping. I'd like to say at most you will gain 7whp maybe more with a tune. The stock 7a produces so little power that it doesn't make a drastic difference, especially if you are only doing a cat back.
i did a custom 3" exhaust for my st215 with a cxracing 3" flex pipe a cxracing 3" cat 170mm hks with a 5" tip sounds pretty gud
Alright, so basically on a 7a it would be pointless to do a full exhaust from the header back? So just a catback would give the same sound effects? Would including a new cat make a difference, or could I not get much better than stock?
From a performance stand point I wouldn't even waste time doing exhaust work on a stock 7a. I'd just save to either swap or boost it THEN do exhaust. If you just want it to sound a bit more aggressive though perhaps someone can chime in since I've never heard how a catback setup sounds.
for 7a, easiest and cheapest way to gain power by exhaust is to put on an ebay header, cat delete or gut it and put it back up, and an after market muffler.... not a lot of gain, but a noticeable difference... intake helps a little too (experience talking, ive got a 7a with this done)
Hmm, well that's some good info. I guess I'll just not worry about exhaust so long as I'm packing a 7a. Eventually I'd love to throw a 3s in, but until then I won't ride around all bark and no bite; that's what makes us different from Honda guys after all.
I'm preparing to get a full exhaust, anyone know of a good system or set-up that produces well and sounds deep? I wanna keep a $500-$600 price range. Any suggestions would be much appreciated guys! Thanks.
buy the materials and have a "good" exhaust shop make it. use mandrel bends not crush bends
Check about 11 topics down. There's a dedicated topic for this with all the info you could want. Assuming you have a NA ST, you'll probably want 2.25 inch piping from the cat back with a resonator. As far as mufflers, it seems that's just a matter of preference. I happen to think a gutted cat sounds cool and race-like, but some people hate the sound.
for a custom exhaust make sure you use good resonators, aftermarket brands that offer it are vibrant and magnaflow, cus greddy for example doesn't sell it separately. if you want a quieter sound you get the oval type resonator and a longer length for example. for your muffler canister, use a good one from tanabe, apexi ws2, magnaflow, etc. they come as universal mufflers so that you can pipe it yourself or if you can get a branded one off another car like a greddy, then cut it off that and custom pipe it after with proper hangars. i would also recommend a custom downpipe since our stock ones are pea shooters, reason i say that is you are defeating the purpose of putting a 2.25 or 2.5 exhaust pipe when the stock downpipe is like 1.75. I felt a difference in sound and feel when i changed this.
and use a good pro bend instead of those lousy bends mentioned by Smaay. wish i could sell you my 5zigen catback, but it would cost a pretty penny to ship it back to the mainland.
I see, its a ST didn't catch that, i recall seeing pure bolt on headers before, you can't find anymore?
My ideal setup would be an ultraquiet resonator from vibrant, and for the muffler, a tanabe universal, apexi ws2 universal, or a cut off a greddy one thats not being used but then again if you could that means the greddy resonator would be there too.
If you plan to get headers, sound will change, a bit louder, sometimes raspier, cus you lose the 1st cat at the exhaust manifold when you replace it. and if yours is not a cali version celi, which has 2 cats, then that would be the only cat you have thus you have no more cats making it straight piped for the most part. Ill tell you that with a cat it sounds better but if you want better flow, remove it, kinda changing the sound a bit, but if your only for sound, the setup mentioned above will work well. it'll be deep and subtle. generic mufflers and resonators have high pitch raspiness
No no the header make the exhaust louder. And he is talking about cutting a Greddy exhaust off of another exhaust setup. Look for the corolla header for the 7AFE it has to have a section welded on to attach to the stock exhaust but if your going with a full custom exhaust it won't matter anyway.
If it were me since your taking the cat away when you get the headers then I would add one later in the piping. Atleast that is what I plan todo. But it is your car do what you want.
i have heard even material of the header makes a difference, cheap stainless steel won't sound as good as DC headers for example. I think he meant to add a cat later, although the cats main purpose is for emissions, it does assist with the overall sound of the exhaust.
