boost creep/exhaust flow question
hello all,
i was wondering if i should expect boost creep with a 4in cat back exhaust..... the exhaust is the apexi GT spec. i know there is boost creep problems with full exhaust but i'm just doing cat back for now or poss. a DP as well but no high flow cat.
while i'm on this note, am i correct in assuming that the 4in exhaust will help the stock twins spool faster? i'm sure any bigger than that and there isn't enough back pressure.
thanks for any help/suggestions.

If the stock cat is in place i would think not but i would expect fitiment issues going from stock to 4 inch stuff. i had a time finding gaskets to fit my Greddy SP cat back to stock in a pinch.
