I am buying the monza mandrel bent catback exhaust from pacesetter, and im wondering if i should get 2.25 or 2.5 inch piping?
i am staying naturally asperated, and i heard from a friend that for a 2.4L engine i should use 2.5 inch piping natrually asperated.
what do you guys think? thanks.
if your staying NA use 2.25 if going boosted 2.5 for less than 10psi for more than 10psi use 3 inch pipe

^ what he said. 2.25 is plenty.
