I need help fixing my exhaust, I have a bad exhaust leak. The muffler sits nice and snug on the muffler elbow, but the flange on the exhaust is broken off and the hole is deformed. I've heard to cut the top off an aluminum can and wrap it around the muffler to seal it. Any other tips? TIA.

Before you yell at me for excluding the baffle, it's broken and I don't want to break it further. It'll be welded soon, but I need the tractor out from its corner behind a bale.
