Ceramic coating and flex connections

[MGV101]

My exhaust header just came in and I am planning to get them coated. Since ceramic coating are virtually unheard of in Hong Kong, I am planning to do it myself.

 

Found a few places where I can order either turbo X or black satin from and I am planning to coat my pipes both externally and internally.

 

Coating the external part should be easy enough but coating the inside may pose a problem due to the presence of a flex joint (steel mesh) in the header as there is no way to mask it off from the inside. Is it ok to coat it as well or would that spell trouble??

 

In addition, would black satin itself be enough to withstand the heat given out by our exhaust manifold or should I really use turbo X? I would probably coat the turbo and up-pipe too if I have enough paint and time left.

I have a general question about coating (as I may get some parts coated when I go to stage 2) ... if it keeps the gasses hotter, isnt that a bad thing? I know it lets off less heat into the engine bay, but I thought we wanted cooler air? Thanks...

you want to keep the heat in the headers for the turbo.

as for colder air..the engine wants colder air ,that's what the intercooler is for ~

as long as the paint your using is ceramic based and heat treated between 2-3k degrees i would think you should be fine. I painted a manifold on my buddies 06 turbo civic with dupicolor 1200 degree ceramic based paint. its holding well but the paint it chipping slightly
