I lost the nipple out of my manifold on my 15 II. Have stuffed lighter exhaust pipe in to hold muffler but it doesnt stay for long. Whats my best bet?.. should I get anew pipe and have it brazed or try to rethread the manifold and screw in a new one. ?

By the way for brazing .. will a map gas torch work or do you nee d oxy acetylene? Thanks Brian S

Did you lose it after removing it, or did it become dislodged and FALL out? If the latter, you may have a situation where someone has chased the threads and left no more meat to cut... but if it's the former, I'd say tap it and thread in the right nipple. Brazing to the manifold is possible, but problematic enough so that I'd suggest pursuing the other avenue first.
