Muffler rattle!!!

Check the heat shields between the cats. The rivets rust out and they will vibrate against the exhaust. Use a rubber mallet and bang around to find the source. It sounds like a tinny rattle.

Solve it with a steel ziptie or a hose clamp. Had this happen on my first box.

I have rear cat delete pipes on so no heat shield. The damn rattle is inside or on top of the muffler. Maybe it’s time for a Fister exhaust😁
