Default Re: easy/safe to weld exhaust pipe with propane torch?

If you get MAPgas (a lil hotter than propane) and a brass brazing rod, you may have a better chance. Although, I don't believe the copper will stay all that strong after the constant heat/cool cycle of running bike, stop somewhere, run bike....
Would be my suggestion just to lug it on down to the welding shop. -bribe a buddy to bring you!
Brass brazing rod will work fine. I made a exhaust pipe (copper tube) for both my son's choppers and to date (3+ years) I haven't had a break. NOTE: I use a oxygen/propane torch.
Looking for HT's parts?
