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. -Matt This post has been edited by GotToyota: Aug 26, 2008 - 9:44 PM |

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 I understand and I agree that it still looks good. What size is your piping? How do you like the muffler? It's one I always recommend. -Matt |

Do you have a video camera so you can get a sound clip for us? And do you have a cat, resonator, none of the above? Tell us more about the piping setup.

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?
OBX EVO : http://cgi.ebay.com/ebaymotors/ws/eBayISAP...hlink:middle:us OBX Apexi WS: http://cgi.ebay.com/ebaymotors/OBX-Apex-i-...sspagenameZWDVW OBX SP: http://cgi.ebay.com/ebaymotors/ws/eBayISAP...em=350106496286 or this : http://cgi.ebay.com/ebaymotors/ws/eBayISAP...em=360090419964 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 This post has been edited by mitchy: Oct 7, 2008 - 3:39 AM |

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 ![]() This post has been edited by mitchy: Oct 8, 2008 - 4:07 PM |

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
![]() 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
