If you got access to a welder,
Then I'd reweld it.
If not,
I'd run it till it gives up.
And Ice is right,
JB weld definetly won't work on any exhaust part.
OK, I'm going to "dry fit" it first on my Rocket, to make sure that there's nothing else amiss with it (like angles of the pipe inlets/outlets and/or mounts), etc. Then I'll go find a welder to touch up that seam.
Guess I now will be painting it thereafter.
I have one of those little MAPP gas/Oxygen torch kits but I'd probably burn a gigantic hole in it, trying to reinforce that bead.... :lol:
Yeah, some pretty crappy looking weld. Do as Tacker recommended, it's quick, easy, cheap, and reliable. Oh, I'm not a welder, but I did stay at a Holiday Inn. 8)
