My NAA came with the vertcal exhaust stack broken off and a Harley motorcycle muffler stuck on the stub. I ordered a new pipe, which turn out to be a nicely bent sheet metal pipe. The issue is that the mufler connects to a casting that seems to have been made in one piece with the original stack. The casting is made with an integrally cast bracket that attaches to the engine for support. To use the new pipe, I guess I remove and toss the casting, and bend the strip of sheet steel that came with the new pipe to make a (flimsy) bracket to support the pipe. I think you have to have seen an NAA exhaust to understand my description. Has anyone else been thru this? Any advice?
