Installation Notes:

Fits 4 WD only. Long-tube headers do not include reducers. Do not use header wraps; they can cause header tube cracking from excessive heat or rust from moisture build-up and void the warranty. Breaking in an engine with ceramic-coated headers can damage the coating and void the warranty. Use cast-iron exhaust manifolds or old headers during engine break-in to prevent coating damage. Ceramic-coated headers require several heat cycles to fully cure before withstanding extreme heat. For additional information about ceramic-coated exhaust products, call Hooker Technical Service at 270-781-9741.
