Jeff,
Little did I know, but I am doing what stainlessheaders.com do is a much smaller  way.  Might be a good place to get a turbo flange, if it is 321.  I have been getting my ss tubing from Burns stainless, fitting, filing and tacking then having a professional friend weld it.  I'm using a Hushpower 2 at the moment and it works well.  It is about 9 1/2 pounnds with ends welded on it and I would like something lighter.  I'll keep you posted.
