Josh: That's some great welding! You do it yourself? If so, as you know, welding seems to be more art than science - it gets tricky sometimes. Is that mig welded?
That 'shell' is pretty thin, as are the pipes (as I found out - thought they were thicker...). One of the tabs that bolt the exhaust pipe to the shell (near the flange that connects to the muffler) had busted at the original weld to the pipe, and I tried to mig weld it back on (just a 1/2" of welding...). Just about had it and was trying to put a finishing weld to a spot, and lingered for a second too long and 'poof' - melted a 1/4" dia hole in the pipe before I knew it! Had it set to the lowest speed & current! Eventually got it closed up with more welding, but made it worse before I finally got it!  Any mig welding tips for thin stuff?
And you're probably right on the JB Weld.
cheers,
jt
