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. Gibson headers are available in nickel chrome plated, stainless steel, and ceramic coated finishes. 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.
Fits applications without air injection and without EGR.
