I strongly recommend you either weld the pieces, or else replace the entire exhaust system, right up to the cat, assuming that's also not a solid piece of rust.

Replacing entire exhaust is probably what I'll attempt... I was planning on just the muff/resonator but I'll check the connection at the cat... hopefully those bolts are decent... thanks for the guidance!
