Been there-n-done that ....   the stainless and the welds won't take the

I'm tired of refabricating another exhaust manifold every 40 hours!!!   I
might call Atkins to have him weld one up for me... Steve McGowan's has
lasted over my 40 hour threshold without a hint of delamination... (the
backfire after shut off is the usually the destructive mechanism... )enough
of this, time to sleep so I can fly in the AM!!

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
206-314-6882.

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.
