I think 3" for turbo and 2.5" for N/A, but I may be wrong. The 3" is louder than the 2.5".

Definately get the 60mm piping (2.5") for your N/A. You can add a Y pipe and/or HFC's or test pipes to increase the sound.

pssst....Sorry to hi-jack your thread...

I just ordered RSR exhaust too :P Gona give it a try. Didn't get any Y pipe yet because I am still debating on which one to get. I am debating between the following Y pipes: Topspeed, JIC, AAM, 5zigen, altered something?...I am leaning towards AAM for now after seeing your results, but still am open to others.

Hey Folgrz, doesn't your AAM y pipe give you better gains? Is JIC or Ultimate racing louder than AAM Y pipe and give better gains?

the ultimate racing/jic are both pretty straight and they look a bit nicer than the AAM

thats the only reason I'm thinking about switching y pipes

Are they better than AAM performance wise or sound wise?

I like the JIC it gave the exhaust a nice flush look and yes the y pipe does look better and it eliminate the exhaust rasp.
