If your planning to go Turbo just go 3" If your planning to supercharger or staying n/a 2.25 or 2.5 will be fine. So think about your long term goals and then go from there but Turbo will deffenetly beneift from a larger exhaust. I made an extra 50 whp between my 2.25 magnaflow cat back and my 3" exhaust dump.
