I think you may be correct on the converter. not holding tune "recently" is a clue...moving to backfiring or rattling in the exhaust. Simple enough to check....drop the converter and look inside. If there are broken pieces or you can't see through the mesh odds are this is your problem. As an interim measure to keep you running you can knock out the ceramic mesh with a piece of wood and a hammer on a piece of plastic to keep down the mess. Try not to make much dust and bag up the debris and throw it away. The housing is stainless on my vehicle so you can reinstall. You've eliminated the back pressure from the insides of the converter so it may not run as well unless you retune until you replace the converter. If the converter isn't it then you need to move on to looking for other culprits.
