2.35 is really what you want. almost all exhausts for the celica are made this way for best down-low and top-end power.

2.5 exhaust will bog you a little bit down low..but at higher rpm's you'll do better.

if your n/a, you really don't want to go higher than 2.5 at all.

Is it even worth it if your NA to do custom piping? And when you guys say custom piping, do you mean from the cat? From the resonator? Or pure straight pipe from the headers?

^^ i'm not gonna say i doubt it, but i am gonna say it's unproven. user bias makes you 'feel' a whole lotta things. put it on a dyno and show me thumbsup

2.5" exhaust is better than the stock exhaust for 'enthusiast driving' anyway. i'm not sayin your exhaust is bad or anything close to it, but i don't jump on anyones bandwagon without proof or a great reputation for putting out proven products previously).

good luck with everything though, chris thumbsup
