Rattle under acceleration
I have a 2017 Camaro SS. It has 77,000 miles on it. I purchased it when it had 75,000. I noticed when I first got it if I was accelerating hard when it shifted it was like a rattle noise. Of course, right away I thought it was that torque converter chatter. The man who bought it new, had the transmission fluid flushed at 25,000 miles because of that and I had it changed flushed as soon as I bought it. There is no lack of power no slipping, shift solid,so I don’t think that’s what it is also, that should eliminate the cats. Great power runs very smooth. Now lately it’s been doing it a little bit more always under acceleration and not easy acceleration, but punch acceleration. It sounds like a pipe or something rattling. Unfortunately I can’t pinpoint it because it doesn’t do it all the time. Any ideas? I read on here that it could be a busted muffler, bracket or that shielding. That is what it sounds like but I don’t know where to look for that other than putting it on a rack. does anybody have any ideas thank you very much

Do you have NPP exhaust? The valves are known to rattle.

Sounds like spark knock. Does it sound like marbles rattling around in a tin can? Are you running premium?
