have a brand new 2021 camaro with the npp exhaust. The car is literally less than a week old.Only 65 miles on it. The car runs great, i just leave the engine sound management in auto mode all the time. it is a v6 auto. Its just that the first "cold" start of the day there seems to be a small "sound" or bang" coming from underneath the car. Then that's it. Car runs great, sounds great, etc...i stop and start the car doing my chores 3-4 times the rest of the day. No problems. Then the next day i wake up and the very first start of the morning there is that loud little "bang "sound. Is that because the car is new, or am I being paranoid, is it the valves on the exhaust? is it the catalatyic converter just waking up, or what? Anyone know what that sound is? or is it just me. thanks. let me know if anyone has any answers....
