i am going to be installing a 14b turbo on my car by the end of the year and i am tryin to decide what to do as far as the exhaust is concerned. i will be getting a 2.5" test pipe from xtremers and i would like replace my muffler as well. i was thinking about getting a greddy evo catback but im not sure if i should get 2.5" or 3". i know 3" is usually better for boost but i will only be running 7 or 8psi till i rebuild the engine and even then i probably wont bring it above 12psi. would 2.5" be fine or should i stick with a 3"?

why would you want to waste time and money? do it right the first time.

If you are gonan buy exhaust might as well make it 3in, why do 2.5 when you can have 3in.

3inch= spool go fast..

thats what i figured, just thought i would check with the experts to make sure beforehand. dont wannt spend 500 bucks just to redo it in the future. thanks for the help everyone.
