On my car, the difference between the stock H pipe and the offroad Prochamber is huge, sounds like a whole new catback. Highflow cats wont be as big of a difference but probbably still a difference.

I've got FRPP shorties, Bassani X pipe (no cats)and American thunder catback from Flowmaster. Sounds great! I get compliments onthe soundall the time. Gotta love it.

go with the o/r h-pipe and a nice set of 3 chamber mufflers if you don't want it too loud...quiet at idle and cruising but screams when you get on the gas
