Hey guys, I'm running a b18 turbo'd @ 7psi for a dd. Right now I've got on a loud and slightly ricey system. I've got 2.5 catback with no cat right now and I'm looking for something to be nice and quiet, not kill my performance, and not hang too low (car is lowered 2". I was looking into the Apexi WS2, really like the way it sounds, but any info on the Greddy evo2 or the Evo2 TT exhaust? Really I'd like a quiet exhaust. Do I risk any backflow/backpressure problems with a quiet muffler or any risk of a bad A/F ratio and running too lean? Also, I need to pass emission, etc. I know you all get this alot...I just want some opinions before I head out and buy one. Thanks!

 

For a boosted application, 3" is the only real way to go.
