    I noticed a small hole at the top to the muffler. Where the pipe connects to the muffler... at the weld.

    There is a tiny hole at the weld and has a circle of black (oil) around it.

    Can I clean it off, then JB weld it? Will that hold?

    There is only one way to know for sure.

    Make sure you use the slow curing stuff, it tolerates temps better.

    I sure do use JB - in a lot of situations - but - for a very hot pipe repair - recommend - simple tack from a Weld Shop.. No harm done if you want to try some JB - I have been amazed many times - HOW GOOD IT REALLY IS !!! Happy Riding from - Mountainman

    So far the JB weld has held up to fix the exaust leak. It has darkened a little bit from the heat, hopefully it stays fixed.

    It will burn up with time, but there is a putty made for that. its sold in the muffler section at Pepboys.

    Yeah I've never had luck with JB weld on exhaust systems. They're just too hot for the stuff. Works great on everything else though.

    A cheap no hastle fix is plug it with a screw slightly bigger than the hole. Goop a little JB
    on the threads and screw it in.

    results are in....

    JB weld will not hold.

    Not too long after I tried JB weld.... a hole formed in the JB weld.

    I will try some of the muffler puddy.

    muffler puddy ??

    well my buddy owns a muffler shop
    never seen him recommend puddy

    when you are tired of playing around
    a little tac (weld)

    does make one wonder though
    will it be breaking in yet another place in time ?
