This part is legal for sale and use on Emissions Controlled Vehicles, in all 50 states, when used in accordance with the manufacturers application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number.

Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Hooker recommends using cast iron exhaust manifolds or old headers during your engine break-in period to avoid damaging your coated damage. Please call Hooker tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker does not recommend the use of header wraps as this will void the warranty.
