    True High-Performance Headers. Help your pickup achieve the highest levels of performance with a set of high-quality headers from Kooks. Aerospace-grade stainless steel tubing is sized and formed to optimize flow at high RPMs. Elevate your ride with Kooks.

    Built to Last. Kooks designs and builds these headers in Statesville, North Carolina. Thick 18-gauge T304-series stainless-steel tubing is formed with firing order in mind for optimal total engine flow. These headers are tuned for ideal exhaust scavenging at high RPMs. The flanges are precision laser-cut and won't warp or break. Kooks covers these headers with a limited lifetime warranty.

    Headache-Free Installation. Headers are one of the more difficult mods to install on a vehicle. Kooks simplifies the process by including all necessary hardware and gaskets. Step-by-step instructions are included, and tech support is a phone call away.

    Application. These headers fit your 2014 through 2018 GMC Sierra half-ton pickup with the 5.3L or 6.2L V8. They must be used with the Kooks Y-Pipe (not included). These headers are not legal for use in California on any emissions-controlled vehicle.
