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

Nothing applied with a propane torch is going to last. The pipe itself will reach temperature hot enough to weaken whatever solder used, then vibrations will do the rest...
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!
