Our Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high standards of quality, We apply a multi-layer inside and outside aluminized ceramic coating in-house and then polish the coating to a high luster. This aerospace and military-grade technology adds excellent protection to your headers while offering the benefit of thermal control in your engine bay. It also improves cylinder scavenging of exhaust gases and increases the longevity of your header investment.
