RE: Cat back?

why do you want it bigger than 2.5"? Are you staying N/A? You don't need anything bigger than 2.5", 2.25" would do you just fine even.

ahhh aight man, didn't know you were going turbo. Tony (Forty04) had a Megan Drift Spec on both N/A and F/I and he said it worked fine for both. Pretty cheap exhaust system too.

RE: Cat back?

N/A = naturally aspirated, not turbo/supercharger, juts regular intake
F/I = forced induction, turbo or supercharger

If you're going boost i'd say just go 2.5" or 3" custom piping.
