  1. Sanderson 5-yr WarrantyThe Patented Leak-Free Design that Sanderson Headers offer you is the only leak-free flange design on the market ... Do Not Attempt To Use Flange Gaskets! The raised flange on the Sanderson Headers will buckle the gasket during tightening and actually cause a leak!
  2. Sanderson Headers are NOT emissions legal on pollution-controlled motor vehicles. It is the purchaser's responsibility to verify local regulations for compliance.
  3. Wrapping your Sanderson Headers with ANY thermal tape voids your header warranty. The best thermal protection for your headers is our Aluminized Ceramic Coating that is available for every Sanderson Header.


Limited 5-Year Warranty (read more here)


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; coincidently, means the RIGHT header is on the passenger side. See the detail image above left that describes engine sides.
