Opps. That should be 0.035 316 SS for the mufflers and not the pipes.
I think the pipes should be something thicker like .065 316 SS near the

engine

and .049 316 SS a foot or two away from the engine.

321 stainless.  I do know that 321 welds beautifully using a Henrob gas

You are right Tracy. I meant the more common 321.
