2.5 or 2.25 piping?

[DC2 Racer]

i am thinking of gettin my piping done next week... and wondering how many inch should i go?? my friends are telling me to go 2.5.. but my question is will i loose power..if i did go with the 2.5?? its gonna be straight pipe no cat from headers to stock cat-back

what do u guys think?

ok, i hope someone corrects me if im wrong, but ya, i think u lose SOME power, not a whole lot at all tho since a bigger pipe means less back pressure... i dont kno if im right, just trying to let u kno wat i think, but i do believe that if u go boost, bigger piping is better. :what:

What mods do you have?
What mods do you plan on doing in the future?

Unless you plan on doing a serious NA build with a high RPM powerband, 2.5 will be too big for a bolt-on's only B18B, and too small for a boosted B18B. Well, not necessarily too small, but why buy a 2.5 inch exhaust for a boosted car when you can buy a 3 inch for less money and get more power?

well right now.. i am gonna be mainly bolt-ons but in the future i am gonna be going LS/VTEC

2.25 should be fine for you set-up

i concur... lol

basically 3 inch pipping if you're boost, and 2.5 if you're planning to build your head and internals.

Damn, i just bought a 2.5 full catback and my mods are, intake,nology hotwires and the car is getting the head ported and polished, should be out tomorrow, so the 2.5 catback is ok? or would it be too much?
