    Well ive always liked the flowmasters and ive never really heard magnaflow so im just trying to decide which to go with. GMPP = gm performance parts right? So does that mean they are relatively quiet? And how is it without the resonator? Everyone keeps saying raspy or fart can sounding?

    With no res, they're somewhat loud with throttle (or during warm up), but not loud at idle (once at operating temp). With the DP they've gotten a bit louder. And yes, GMPP is GM Performance Parts

    Like I said, I get compliments from LS4 owners so it can't be that bad.
