ya, 2.5 will work for you. NEVER GO 3 inches unless your turbo'd.

Anything above 2.5 on a n/a will be nothing. You need... well want... back pressure.

ninja edit: Well 3 inches if you just want to be a douche and have a really loud exhaust.

i know i need as little back presure a possible and a lot of velocity. i was thinking 2 3/4 but its a rare size.....
