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 BlackHeart 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. |
