ok, i'm currently still running cats and stock manifolds, all through 2.5" exhaust. i can't imagine it being a problem.
a couple of the local people i've talked to recommended the pro street 6000 series. can anyone chime in with experience there? or know how they compare to the 9000 series?
thanks for the advice.
