I know Karl has a set of these, but I see they have a standard flange that would mount up to a European Racing header. I think I might try to sell off my ass, I mean some excess stuff and pick one of these up to try. Any comments?

Not a standard flange. They come with a clamp-on fitting.

(i.e., I got some stub pipes made with a flange on one side. The slip inside (tolerance fit) the Coast mufflers, and then you clamp them down with heavy duty stainless clamps.

Here is a picture...

Oh.....well, one could weld the triangular flange on, right? How much do they cost?
