custom exhaust set up

33 21.26.3.25.0 · 10-08-2005, 06:10 PM

ok. im going for single outlet. my friend supplied me with rsx s (06) cat back. im going to do custom piping (2.25 in) with the resonator. then im going to powdercoat it black. hopefully i get some kind of gain with the single outlet (~2-3 whp?)... (this should be a really quiet set up too) what do you guys think?

I like the powercoating it black idea....would love to see it~

If I were you I wouldn;t change from my "2 exhaust system" to "1 exhaust system" dude ... 2 is much nicer than 1

just my 2 cents comment. dont forget to post your picture when you have installed your exhaust.

yea that is true. the 2 dual exhaust looks nice, but it isnt ideal for a 4 banger car. dual exhaust are better for v6 and up. plus i got the type S so i wouldnt have to mess with my stock (so i could put it back on) thanks for the input though!

Not that I know anything about this stuff, but as long as the split is far enough back, why would a dual be worse? I mean, I understand that a dual is better for a 6 or 8 when you have separate headers and it's dual all the way back, but in the TSX, the split is way back, past the resonator.... Why shouldn't it just look like a single as far as the engine is concerned? Just wondering!

the split causes the ehaust gases to slow down a bit, no matter where it is. think of a water hose; when you put on a T to the end, doesnt it slow the water down? also the straighter the piping, the beter / faster flow. you want the lease restrictions if you want any gains. IE im planning to make the piping diameter a little bigger with a straighter design. also why do the most circuit cl7 (N1 exhausts) and ap1/2 run single exhaust instead of the dual? ;] i hope this helps. :]

Yep, a Duel exhaust on a 4cyl is rediculious, looks great but powerwise its crap... The only reason the old V6's and v8's ran real duel exhausts is because they have 2 headers... The TSX is a Longitudinal 4cyl, and only has one Header and a single piped exhaust will make the biggest gains, especially if you Replace the Catalitic Converter, as I have long suspected recent dyno's have proven that thats one of the Archiles Heals on the TSX, You run a 3 inch pipe Strait from the header, run it to a Highflow cat, and then follow the stock path with a 3 inch pipe to a single muffler, and your gonna get some nice gains, and a great sound too... good luck...Id love it myself I could afford it

They run single exhaust because even if it gets 1HP, it may be worth it in a racing environment. They do a lot of things that you wouldn't do to your daily driver.

I personally do not like the overly-raspy tones from the typical N1 style exhaust. So, I can pretty easily make that compromise for less power but more sound to my liking.

In theory, I'm sure you're right, that the straighter, the less, etc., the better. But I can't help but feel that, as long as the pipe is sufficiently large, that a well-designed split should be a big deal. The T in the stock system may not be the best way to do the split, but as long as we're talkin' theory, let's talk about a half-way intelligent dual design.

I'm covering this in relation to this thread.

Forget the theory, if you want to measure the twin-pipe output of the CL9. It goes from approximately 2½ inch after the catalytic converter, then to 2 inch before the first resonator dropping to a 1¾ after the second resonator inch each way follow by the standard OE restrictive muffler for virtually zero noise emission. It is ultimately still a single pipe even if you were to weld-off one muffler for whatever reasons and will retain the same output.

Yes, a single pipe will give you that "raspy/boom" tone which a twin pipe won't on the CL9. To cope with that, a single pipe or twin pipe uses resonators to control that.
