Holley Performance Emission Code 4: This part is legal for sale or use on Racing Use Only Vehicles. The following vehicles are considered Racing Use Only Vehicles: Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street. WARNING: It is against the law to install this part on an Emissions Controlled Vehicle
Installation Notes:
NOTE:-Will not fit with angle plug heads or raised port heads. Installation requires air conditioning bracket 10925HKR left side or 10926HKR right side.-Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Hooker recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating 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.
