You'd be surprised how the inside turns out of not 'process' welded like this. .

Ya in my home shop I'm only setup for MIG (but I can run SS wire). I have done some tube on TIG using a dual-reg and purge dam when welding SS pipe before.
What weird is that right now I have the (
old) Mangaflow SS mufflers, but a mild steel exhaust and never had a reaction (galvanic?). I think the inlet and outlet on the muffler are actually mild steel, and the welded with 309l or Silicon bronze or something, since the center section is definately stainless.
