    Airtight Fit. Since headers are designed to increase flow and decrease back pressure for a more powerful exhaust system, you need an absolutely airtight fit between aftermarket and factory parts. The port flanges on these Gibson 1-3/4 in. Performance Headers are laser cut to ensure a tight fit and optimal pressure for maximized performance improvements. The 16-gauge stainless steel tubing features a ceramic coating for extra corrosion resistance.

    Simplified Installation. Many other headers require welding or modification of other exhaust system parts to get a good fit. Since these Gibson headers are designed only to fit specific vehicles and models, these parts are customized for easy slip-on installation directly to the cross pipe. All the necessary hardware and gaskets are included, and there's no concern over voiding your warranty.

    Application. This pair of Ceramic-Coated Gibson 1-3/4 in. Performance Headers are designed to fit the 2014 to 2018 5.3L and 6.2L GMC Sierra's without the EGR.
