It’s finally warmed up enough to try to track down an annoying thump from the rear of the 1999 Camry when I hit bumps. It turns out that when I replaced a couple of sections of the exhaust, the muffler seems to have moved back a quarter of an inch or so, and the rear flange now bangs into a bolt head when the muffler bounces. I fixed it temporarily with a wad of aluminum foil folded over about eighty times, but I doubt that will last. So I think I need a permanent pad/spacer made out of something soft and heat resistant enough to stand muffler temperatures. In a cooler spot, I’d probably use duct tape, but sticking duct tape to the muffler seems to me to be a bit iffy. I’m sure the stuff will burn if it gets hot enough. Anyone have any other thoughts? ---

Forget the duct tape. Check out the car parts store, I bet they have something that’s made for exhaust systems/heat. ---

The muffler moved back 1/4" or so? Unless you determine why this happened it’ll probably keep moving. Once you solve the problem, you may regain the 1/4". For the record, parts stores sell muffler repair kits with a fabric-like material and a liquid-steel type of material that is intended to repair exhaust systems. I’ve used it on a rot hole in a very old cat converter with excellent success. But in your case first you need to determine and solve the cause that moved your muffler back. ---

Aftermarket bolt on exhaust parts could have caused the shift. ---

If you loosen the clamp at the front of the muffler you should be able to drive the muffler 1/2 " deeper over the pipe. Use a flat block of wood and hit the wood, not the muffler. If you can’t ,then take the muffler off the front pipe and trim the end of the front pipe 1/2 ". ---

Steel wool would work, but will disintegrate over time. You could also use mineral wool pads.
