Thread: Headers, wrap versus paint or coatings

Tweet

Ceramic coating any header, whether it is mild steel or stainless, serves a number of purposes. With mild steel the longevity factor is most important where as the stainless (if it is "real" stainless) not so much. The best reason to coat a header is heat reduction in the engine compartment. A coated header retains the exhaust heat inside the tube. The coating prevents a major amount of heat transfer through the steel. The coating has to be done inside and out for this to be most effective.
JetHot is highly recommended as they coat inside and out. Not all coating services do. http://www.jet-hot.com/
Do not wrap your headers with any kind of thermal blanket or tape. There is nothing to gain and it only shortens the life of the tubing as stated above.
