Opps I forgot to include the Inconel guy.

Yes, I do know someone who can fabricate Inconel exhaust manifolds
reasonably for Mazda's. His name is Mark Sedickas who owns Mark's Welding
and Fab in Graham, WA  Days-253-852-0540, evenings 360-893-5528. pager

Mark did my exhaust manifold (turbo 20B) for about $300 (it was p/o a lot
of other work). He gets scrap cuttings of inconel sheets from a local
source, and then he rolls it (min 2.5" dia) to make manofolds and

mufflers.

Dave Atkins sends him a lot of work. He is a certified Aircraft welder and
does beautiful work.

Chuck is right on with the right guy to do the work.... but the cost is
tremendously greater (X3)... my expectation for a $300 product cost me $900.
Still a beautiful and timely product though.  I feel I got taken by Mark if
he only charged Chuck $300.   I had a 90 degree perferated turbinator welded
into the tangent to disturb the rotational turbulance.... absolutely no ill
effects at all on the back pressure or the high end... and the Inconel
sounds sexy!!!
