Exhaust Leak

[Tuley11]

Has anyone had to deal with their cat going bad and starting to leak?

Trying to figure out what’s the best move to fix it

I have not. Also moving this to ask an off road tech area.

Catalytic converters don't normally 'just go out'. Some diagnostic work needs to be done in order to determine the root cause for the failure. Often times we see car in the shop that have a blown head gasket(s) or excessive engine oil blow by that will contaminate the catalytic converter and cause it to stop working correctly.
Also, the problem may lie with the oxygen sensors.
What led you to the conclusion that the catalytic converter(s) are bad?

The code that’s throwing comes back is either O2 or the cat. I’ve got 200k miles now but have no oil burn or indicators of heavy blow by.
