highlander.... You know companies like jethot and jet coat and nameless others do this all the time right...
as far as for the header/exhaust manifold
Ceramic coating doesn't mean ceramic coating... the different properties from one to the other can make them TOTALLY different.. even the color of the same formula can DRASTICALLY effect the results... black will retain more heat and take longer to disapate the same amount of heat as the same formula in white will...
I think highlander is talking about using this EXCLUSIVELY for the intake pipe not the header/cat...
NO there is NO reason to do the cat back or even the bottom half of the header... if it isn't radiating into the engine bay you could care less about it...
Lastly I wouldn't pay for high temp coating on ANYTHING that wasn't turboed... there's just no need for it... as I said with the intake pipe.. the air will just get hot before it reaches the combustion chamber anyway so a 3-10 degree drop in the 2 foot of intake pipe won't effect much. If I WERE to pay for a high temp coating I'd be sure it was one specifically designed for the automotive industry seeing as how there are already 10-1000 companies that do this already and have lots of satisfied customers behind them.
not to shoot you down but it's pretty pointless... you might as well use some of that ceramic spray paint... I'm sure the effects would be similar.
