Hooker Competition Headers are made from durable 16-gauge steel and have 5/16 in. thick flanges that are heavy enough to maintain header integrity, yet pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to increase performance. Will No fit heavy-duty models. 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. 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.

Coming from humble beginnings in 1962 when the pioneer Gary Hooker designed a header for his Chevy, Hooker Headers slowly took root in South Ontario in the subsequent years. This lead to an arms race on who could dish out the best exhaust systems in the market - fortunately, Hooker had a dedicated team of engineers and technicians that toiled countless hours away to design a competent line of exhaust components and systems that produced significant power gains in a balanced engine to exhaust ecosystem. Hooker products gained more acclaim as the 70s and 80s rolled in, becoming the first choice of drag racers when it came to headers and offerings like the straight-thru glass pack mufflers becoming the craze of these motorheads.
