Ceramic coating not only keeps your headers pretty, but keeps the heat inside the header to aid with scavenging and also keeps under hood temperatures down. The only “true” ceramic coating is the “Jet Hot” system. A few manufactures employ this method…and they’re usually the more expensive of the bunch, but for good reason. Some, like Mac use a cheaper method to coat their headers, which is nothing more than glorified paint coating, which usually flakes off within the first 6-months.01Steeda said:I would assume ceramic coating helps alot, but to me I dont see the point.. I cant even see my LT's from under the hood.
