    It doesnt look like any special clamp is going to solve your issue....the clamps you have should work fine. I agree, welding is the best option to seal it up.

    I preferred this type of clamps over the u bolt type... seals 100% and doesn't distort the pipe, makes it easier for disassembly after. Plus it just looks so much nicer.

    This won't work if the pipe is distorted though, if the pipe is distorted due to being crimped by a U bolt clamp such as in your case, it must be straightened first by using a pipe expander tool.

    Does the lack of a relief hole in the muffler play a role? Mufflers so far to the rear of the exhaust system tend to not get hot enough to burn off the excess moisture especially on antique cars with limited driving time.

    Not sure how those clamps work when close to a bend. Do they? Seems like they would need a minimum amount of straight pipe. It looks like the OP's pipe starts the bend right out of the muffler.

    They do come in different widths...
    If the OP decided to go this route, he could pull the pipe from the muffler a little to lengthened the straight part of the pipe and then seal it with this clamp.

    I wonder if high temp exhaust sealer would work if you jammed it into the cracks if tightening the clamps doesn’t work.

    Get it welded, take some steel wool to that surface rust and be done with it.
