Same here guys. I'm pondering on whether or not to buy the Flowmaster scavenger x pipe. I'm more interested in sound

If the AFM valves decide to rattle down the road, then I think I will buy it because the X pipe comes with a pair of AFM valves. I heard Chevy replaces the whole catback if the AFM valves break or rattle.
PPS. If you want your system even louder, pull fuse #51 and the NPP valves will stay open 24/7.
