        Hey Bob, don't get mad, but it could have been your technique?  The weld
area has to be prepped and scoured like any other surface adhesive to get a
grip.  On a pressure sensitive application like exhaust, an area around the
hole sufficient in size must be cleaned pretty well and plenty of JB weld
evenly applied so it will harden into a good bond.  If the weld is 'lobbed'
on piecemeal, this tends to make a weak weld. Applying a significant amount
to the entire surface area quickly and leaving it alone tends to make a
better, stronger, secured bond.
        But who knows how you applied it, or how much experience you have with JB
Weld.  From your description, however, seems like you could re-do it and it
would hold just fine.  Try the trick I described with the tape ---
        If you didn't see that, let me know if you are interested.
