Re: ceramic vs stainless headers
Here is where the disconnect happens... Ceramic coating is an INSULATION. Its sole purpose is to retain the heat within the exhaust system... resulting in lower under hood temps, which can lead to improved performance. The fact that it is shiny, is an added benefit. It was not developed for its eye appeal, it was for its insulating properties.
There is also a black ceramic coating that insulates better than the shiny, and retains a near new finish for a very long time.
Stainless simply resists rust & corrosion. (looks nicer, lasts longer than steel) but, does nothing to control heat issues.
nothing stays new if it is used.
My good judgement is the result of my experience... although my experience is the result of my bad decisions !!!
