While ceramic coating on the OUTSIDE of the header WOULD result in lower surface temperature, there is the theory that the coating also would keep some of that heat inside the header tubes as well which WOULD NOT be desirable as you would want to extract that heat as quickly as possible AWAY from the engine..
