I have 3" but most people have 2.5" I'm not sure if it matters for a FI car or not.

What kinda mods or future mods will be done to the car?
2.25" seems to be working good for NA with some mods. 2" will also work. 2.5" with alot of mods should be good.
3" if you're going for forced induction.

hey it's intake...my bad :D
I'm talking about exhaust. Without a bigger bored out tb, 2.5" should be sufficient.
