Ah, ok, I see now.

Still, can you mount the tube directly to the exhaust manifold? Or isnt' there a spot flat enough? (Hammer? LOL)

I've never welded stainless, but one of my neighbors welded a stainless catalytic converter to my normal mild steel exhaust tubing for me. He said it would eventually break the weld, but it never did. :shrug:

Probably if it were me, I'd have someone either build up an area of weld, then drill/tap it to bolt the flange directly on, or weld a plate to the header and do the same. (or just some studs and drill a hole)
