im used to 3.0s and 3" exhausts. Its very nice and can defenatly feel the difference. But im a bit confused if i really need to go that big on a SR20? Would a 2.5 be sufficient up to 350hp at the wheels? Since the lower displacement would mean higher rev to spool correct?

wouldnt a SR20 with a 2.5 exhaust be beninificial in quicker spool, less turbo lag, more quiet and good for up to atleast 300HP at the wheels?
