Sanderson’s Ceramic Coating is recommended for every vehicle application and is the default finish selection choice above. To meet high standards of quality, Sanderson applies a multi-layer inside and outside aluminized ceramic coating in-house and then polishes 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.
When sitting in driver’s seat and engine in front of you, the LEFT header would be the Driver’s Side on LH drive vehicles; coincidentally, means the RIGHT header is on the passenger side.
