I don't have gas for Stainless either, lol, but That's the metal tubing I bought (the cheap summit SS piping). I bought the right wire for my gas mig, but probably will just use my regular 2 part gas and just expect the welds all the get rusty. Even if u have the right gas u will get rusty welds over time unless you correctly back purge it which I won't be doing. My thinking was, it's better to have the welded areas get rusty than the entire exhaust. I may be seriously flawed in my thinking. Haha
