If you overheat stainless it will get dark and lose the shine. Also you need to have good argon coverage whenever it's red hot. Be sure to keep your torch over the weld after you stop the arc, and you might even need trailing coverage if you weld longer runs. For an inch at a time you should be ok with just the torch. Also you will need back purge for tubing like that.

what size of cup would you have used if you was welding this rambozo?

Since I would only do short welds on stainless exhaust tubing, and move around to help control the heat put into the part, and warping, I would probably use a 1/16" tungsten and a #7 or #8 as long as I could get access with it.

Your filler is regular steel, from what I can see of the copper color filler in the pic and I suppose your metal is as well? It won't give the heat lines like Stainless.. Also for a shinier weld, adjust your argon flow up or use a gas lens or a smaller one.
