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.

2.5" 304 stainless, mandrel bent, header back, with generic ebay resonator, and magnaflow 14" muffler.

first, the 2 into 1 merge collector from the stock header, with 2.5" pipe massaged to fit"





finished b-pipe



center section with resonator



over axle and muffler



a few installed. sorry, i dont have a lift, so its hard to get pics of the whole thing at once under the car while its on jack stands.

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.

If your talking about getting dual exhausts I would say thats a big no no! I would get a resonator with your magnaflow exhaust if you dont want it to sound raspy.

I was looking on the C-one website on the exhausts for the ST202. I noticed that it says 93 db approximate exhaust note. What does that mean. How do they measure the db level.
If you look here at this youtube video of different exhausts for the s2000 you will see 3 different exhaust db readings. one is listed idle, stationary, and racing?

so how loud do you guys think the C-one exhaust is at racing db levels???

noooooooooo no dual exhausts for me.


but after a lot of reading and lots of time in the chat room i decided on magnaflow resonator and muffler

can anybody answer my question??

can anybody answer it now? how about now?

I have 2.5" pipe on my car. it was not a "kit" I sourced the parts and it was all put together from a local exhaust shop. If I was going to do it again, I would have just let the exhaust shop buy everything themselves.

As for performance gains between 2.36" and 2.55"? The only thing that I can say is that 2.55" has a 16% larger cross section. However, I do not know to what extent that will affect performance.

alright cool thanks for attempting to answer my question. I appreciate it. Ya is there really that much of a performance difference, hmm how I wonder?

Now if anybody can answer this question (below) I had earlier please!?

I'd email C-one and ask them for clarification on the dB levels and how they came up with that reading.

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




though dont know how the rest of the world does theirs?
