Hi, mine is a 17' SS 6speed with over 66k miles now with stock NPP exhaust. I took videos of my car when new and was well aware of the crackle and some popping when letting off the gas and during downshifts etc. I was never a fan of the C and P's. Today I was looking at some more recent videos and noticed all the C and Ps are gone, just rumbles and deeper pitch. Anyone else with higher mileage and stock NPP notice this? I assume the metal in the mufflers are now seasoned from age, hot cold temp changes etc. Now I just still have the Snap without the crackle and pop. Sounds so much better than when new. Sounds similar to the old 69 302 z/28 stock chambered exhaust minus the lope of the cam that a school mates brother owned.
