Super Competition Side mount headers deliver the most aggressive style and performance for your early Corvette. Side mount headers are built from lightweight 18 gauge tubing. Side tubes slip directly to the collector for a leak free seal. Hooker side mount headers and side tubes come with 3 choices of coating; show quality chrome, high heat resistant black paint and Hookers Metallic Ceramic Thermal Barrier Coating. Replaceable Hooker mufflers are available separately in 2 different styles; glass pack and reverse flow. The glass pack style provides the highest performance with minimal backpressure and sound control. The reverse flow is designed for maximum sound control.

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. Hooker long tube headers do not come with header reducers. |
