wondering which pipe size to go with ?
Posted: Wed Dec 15, 2010 9:36 ami wanna keep my cat in my car so i was wondering if i should do a straight 2.5 or 3" pipe all the way back with no muffler, or 2.5 with apexi N1 muffler.
Do the latter, 2.5" with the N1. Unless your car is turbo'd there really is no need for 3" exhaust and even 2.5" is kind of pushing it.
Personally I'd go with 2.25" but that just me.
