Our Summit Performance® headers are manufactured from mandrel-bent tubing for superior flow and greater horsepower. The headers feature a pressure-formed collector for a better flow rate and a JIG-welded tube-to-flange plate for a perfect fit. They're made for off-road and racing use only. 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. The headers are available in a wide range of styles, sizes, and configurations. Order the pair recommended for your application. (Special warning regarding Summit Racing™ painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.)
