Every Gibson Performance Header is Dyno-tuned and engineered to deliver more usable horsepower and torque at low and mid-range RPM highway speeds. Improves engines ability to breathe and cooler operating engine temperature. Designed as a direct replacement for the factory manifolds, using the stock crossover pipe. They are well suited for lowered and raised vehicles, street and off-road. 50 State Street legal. Meets EPA and CARB requirements. Will not affect the factory warranty. No welding required. Uses OEM style connections. 3/8" Heavy Duty Laser Cut Port Flanges- No Warping or Leaking. Premium Gaskets and Hardware included. Backed by a Lifetime Limited Warranty.
Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components and adjacent parts can vary between LHD and RHD configurations. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.
Gibson headers are performance-tuned and engine-matched to unleash your vehicle's full potential. These headers are well-suited for lowered or raised pickups and tow vehicles—because the performance gains are engineered to come in at low and midrange rpm highway speeds. They feature mandrel-bent primary tubing for increased flow, and they bolt on quickly and easily. Installing Gibson headers will give you increased horsepower and response and a cooler-running engine.
Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom altered parts, then it is the installer's responsibility to verify fitment. Gibson headers are available in a variety of sizes, configurations, materials, and finishes. Order the model recommended for your vehicle.
