Pics of a custom header for a 1200 HP Honda Here's a few shots of a wicked header for a 1200 HP Honda K20 we just finished. This is pretty much as good as it gets in regards to forced induction header construction.
1/2 inch thick 304 SS flange, 16 gauge 321SS primaries, tri-merged double slip 321 collectors with a 60MM wastegate flange.
Then it was coated in 2500' turbo black,cured, followed by a re-blast and coated in chrome.
Not my thing but you have to appreciate an engine that makes 1200 from 4 cylinders still with 4 bolts around each cylinder for gasket sealing.
That's soap residue you see on the flange

Nice manifold, but my question is how well will the chrome ceramic coating hold up to the heat a turbo manifold see's....with a base coat of turbo black? Will the shine hold up for a long time with it coated in the way you describe.......

It will hold shine better... but the point of the sub-coating is for thermal management. The chrome coating may hang on for surface temps beyond what it is rated for, but it loses its thermal insulation properties. The turbo black coating keeps some of the heat from reaching the chrome coating.
