Default it's all wobbely! my pipe that is, help for fix?

I was out my 2nd test ride, a little longer.
Seemed like everything was humming along. The she started sounding lose up and vibrating. I limped back and found the chain tensioner, kinda expected that, but the I saw my pipe danging and wobbling. I let it cool of and took the pipe parts out of it. It looks like the welds broke inside that hold the header pipe to the muffler part.

Help! I don't weld or know a welder. Can it be soldered? Braised with some kind of propane torch? A special, cheap, clamp? Any ideas other then welding?

Thanks,
Pat Jr.

Would this work?
- J B Weld Stick

Maybe some good old JB Weld?

JB won't work. Do you have a picture of the pipe? Stock?

Hello Bikeguy Joe and Cabinfeaver1977,
Thanks for the replies. OK it wont hold up. I think I'll try the wire and JB Weld until I can get a pipe for it.

Thanks Again,
Pat Jr.

I've held my tongue long enough....sorry if I offend.

JB Weld is a cheap, cheesy fix if it is a fix at all. It will not work for this application, as Bikeguy said, and unless it is just used as a filler, it is, at best, a temporary band aid.

Brazing will work, but use MAPP gas, not propane. However, if it is a chrome part, enough heat to braze will discolor the chrome quite a bit.

Hey HoughMade, don't hold your tongue, let'r go! I need all the tips I can get, but on the cheap side please! Where can I get a stick of the brazing rod?

Thanks,

2nd test ride?
How old is your kit?
Where / who did you buy it from?

Sounds like your broken pipe should be covered by the sellers warranty
Did you get a warranty?

Is there a stub on the muffler left?
Chrome?
black?
Catalytic?
Posting a pic would be helpful for a temporary fix

Where on earth are you?

Good luck on getting back up and running ....

right now I'm in Louisville, KY

I got some Brazing rods at HomeDepot and I used some map gas, the yellow bottle.

I heat, and I heat, and I heat, and I heat, and I heat, and I heat, it wont melt and the pipe wont turn red. I must be doing something wrong.

Is this the right rod to use?

It's just the regular black pipe. The tack weld or sweding came loose inside where the header pipe goes into the muffler part.

Thanks tons guys,
Pat Jr.
