A oil filter wrench, should help you loosen it. if its the metal version, just put something on the pipe to protect it.
But if you start torquing on it, put some blocks or a small jack under the pipes so that you don't separate the junction from the rear down tubes.
I just grab it and start pulling back while giggling up down left right round and round. And a little penetrant. Takes a little time put always works with no damage.
NOTE - there should be a screw through the muffler and midpipe that is covered up by the clamp. Make sure its out before you try pulling the muffler off.

Header probably gets hotter than the can right? Here is a Kerker 4-2-1 collector I coated. Just ask your Coater for "high temp" rated powder.
Last pic is a Kerker baffle done early on. No peeling or melted coat but tell coater to be careful taping off area that is slip fit into can. Its already tight from Kerker.
