If you're driving a little more spirited and hit some downshifts to accelerate then it becomes more noticeable. Overall though the stock NPP has a damn good tone imo.

I also have an M6 and pretty much have it figured out how to drive around them. Mine pops pretty hard during shifts when lifting off the throttle, but the RPM range for the pops seems pretty tied to 2000-2500 RPM range. When shifting from 1st to 2nd, and second to third, I shift right around 2500 to bypass them. If I'm just doing my local cruse, right after I have shifted to 3rd, I shift to 4th at 2000 and am cruising in the 40-45 MPH range. Hardly ever with that pattern does my car pop. If I do my shifting anywhere between 2000-2500, pops are plentiful. They do seem more pronounced when the car is cold. I also tend not to downshift much during normal driving when slowing down, as I was taught that wasn't as healthy for the transmission. I don't have experience with the A10 in a Camaro to know what conditions create them. I have the Flowmaster NPP axle back and drive in sport mode most of the time. I couldn't really tell a difference in the amount of crackle and pop noise when going from stock NPP to the Flowmaster. Flowmaster did increase the volume of the exhaust I'd say 15-20 percent at a guess, for sure made the tone a little deeper. I'm an old guy so I like the Flowmaster tone.
