I'm going to go pick up a BBK O/R x-pipe this weekend for a good price. I know its not going to have a clean x-pipe sound like a true x, like slp, upr and vrs x-pipes. It should sound pissed off at WOT, i'm interested to see how it sounds down low. Anybody running a MAC catback and BBK x-pipe? How do you like it or dont?
