Select your GMC Headers model from the list below.

Pacesetter Headers

Manufactured from corrosion-resistant, 16-gauge aluminized steel, the Pacesetter headers will surely boost your GMC's horsepower and torque output. They're a great investment for those who love to go off the beaten path as these headers will also improve your vehicle's off-road performance. A part of the brand's family of Quik-Trip Long Tube headers, this header kit will surely streamline air flow for a more efficient performance. The headers in the kit feature thick machined steel flanges. You are provided with a choice of coating--either ArmorCoat ceramic coat or black-painted finish. Made in the U.S.A specifically for off-road applications, the said Pacesetter header kit is 49-state legal--it can't be used in California. Also, D-I-Y GMC owners won't have a hard time installing this kit in their ride as it comes with adapters and mounting hardware. The kit is offered along with Pacesetter's 3-year limited warranty.

Gibson Headers

With their promised torque increase of up to 30 lbs and horsepower boost of up to 20 hp, the Gibson headers will provide your GMC vehicle with unparalleled performance whether on the racetrack or on the street. Sold as a kit, the header features 3/8" heavy-duty, laser-cut flanges that are guaranteed to be warp or leak resistant, as well as natural, stainless steel finish that's proven to withstand corrosion. It also ensures easy bolt-on installation with no welding required, so DIYers can have it fitted into the vehicle in less time and effort. Manufactured in the U.S.A, Gibson headers will surely make the engine last long in service by making it operate at favorable temperatures. These headers will improve your vehicle's overall efficiency, therefore achieving better gas mileage. Gibson is so confident in the quality and durability of this kit that it backs it up with a lifetime limited warranty.

JBA Headers

To deliver optimum horsepower increase and torque gains, the JBA headers are engineered using race-proven technology. Available as a kit, the said header features primary tubes made from premium-quality mandrel-bent stainless steel material that's titanium ceramic coated for excellent protection and corrosion resistance. These Cat4ward shorty headers also boast of a patented JBA Firecone collector, ultra thick collector domes that ensure durability, as well as factory-style emission connections to match the components they will be connected into. These headers also come with CNC laser-cut flange and exhaust ports that are oversized for maximum exhaust flow. The said headers are 50-state legal, so GMC vehicles fitted with these can be driven anywhere in the United States. Besides improving the vehicle's throttle response, the said header kit is also capable of resisting warping and allowing cylinder head porting. It is designed for vehicles that aren't fitted with EGR.
