Exhaust pipe repair ?
Ya thats what I should try. Muffler tape with a clamp. This all I can do at this time. I really don't want to have acomplete weld, so when I have to work on the car I could remove the exhaust with out having to cut it up again. A removeable cuppler should have been installed for future removal.
Maybe this might work beening that the cut is past the muffler and less back pressure. I don't know.
