thanks fellas. It is coming along, and I hope to have this thing on the road in a few weeks.

The 880 rod was reccomended to me by the guys at the County welding supply store that I go to often. Since I will be doing tig weldign on various metals, I needed something that could be used to join different metals. I do have some stainless filler rod (I forget the number) but it is 3/32" and would probably have been too big for the v-band flange there. On the opposing/mating v-band flange (which is stainless) I will have to weld this to my 3" diameter collector pipes which are aluminized steel. I never planned on doing a full stainless collector pipes, especially since the flex-pipes are not stainless anywhere. The o2 bungs are stainless, but all the 3" pipe is not. So the Weld-Mold 880 rod is what I decided to use because it is considered to be the best affordable multi-purpose filler rod for dissimilar metals, at $28 per pound.
