Hey I am gearing up for a BIG BOOST setup (15-20psi). I want an exhaust that sounds good but also lets my turbo breathe. I know 3" piping is preferred but would 2.5" suffice? Also what would i need to make it sound good and not like a tin can? Huge resonator? Any specific exhuast systems u can recommend like sp2 or somehting. I like the sound of the WS but that blows for turbo...

PLs Help!

 

You will be ok. On an old setup I made 322 whp (i forget tq #'s) on 10psi boost and going through 2.25" apexi exhaust. Of course the bigger the better in this case, but you should be ok.

 

ok so how would i ake it sound deep and not like a tin can (aka most hondas)

 

The turbo acts like a muffler ne-way so even without a resonator it still, in most cases sound deep.

 

2.5" piping from Kteller, a turbo style muffer and maybe a 3" DP and 3" cat would sound nice on most hondas. Pretty deep note.

 

"The best exhaust for turbos is no exhaust" -Corkey Bell. If you dont want the sound, just keep what you got and use an exhaust cutout. What I'd like to do.

 

ive seen mid 400's on a greddy evo exhaust which is like 2.3 inchs i think

 

isnt a large dp to smaller exhaust counter-productive?

 

do you think the greddy sp2 would work?
