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.NOTE: These headers were not designed for bolt-in compatibility with a 4L80 transmission. The ears on the side of the transmission would have to be trimmed for clearance to permit the installation of these headers. |
