ceramic coating costs

[Ameer Antar]

Hey, has anyone done/priced ceramic coatings for their 5kT exhaust parts? I
am planning to coat the exh manifold and turbo turbine housing, possibly
the down pipe as well. Since it's a turbo and (judging from my manifold),
I'd need the 2000 degree ceramic coating. I got a wide rnage of prices. One
said $120 for manifold, $60 for turbo, and $15/ft of pipe. Another one (not
JetHot) quoted $350 for the manifold, $80 for the turbo, and $65/ft. That's
quite a difference, but they both say it's the high-tech 2000 degree
coating. Any ideas on what's making that difference???

Also one of my turbine housings has a crack inside near the center. Is this
worth coating and anyone have any leads on a crack-free turbine housing?
Thanks again everyone.
