Headers
All Doug Thorley Header models are constructed of 14-gauge steel for ultimate longevity. Custom designs and tunes are engineered to perform and fit flawlessly under your hood. Coated inside and out with a Ceramic-Thermal Coating that protects your header from the elements and withstands up to 1,400 degrees F, these Doug Thorley headers promote exhaust velocity and absorb up to 40% of the engine temperature to keep your engine cooler and running more efficiently.
When it comes to enhancing horsepower and fuel efficiency, nothing matches the value of Hedman headers. These Street Hedders are crafted with top-notch quality, promising a lifetime free from any defects, including tube and weld cracks. You can choose from black painted versions (note that this paint is temporary and intended to protect before installation), and you'll be pleased to find that all necessary gaskets and mounting hardware are included. Generally, these headers are tailored to fit vehicles in their original factory condition, meaning they are compatible with factory-installed components like cylinder heads, chassis, steering, motor and body mounts, and bushings. If, however, your vehicle features aftermarket parts, components from other makes and models, or custom modifications, it's crucial for the installer to ensure compatibility.
LS1 Full Length Engine Swap Header fits popular muscle car applications. Hooker swap Headers are designed to provide an exact fit. Hooker swap Headers add the extra horsepower and torque the serious enthusiast demands. Hooker Headers are the best single improvement you can make. These headers are silver ceramic coated.
At Classic Performance Products (CPP), we pride ourselves on delivering top-quality parts from trusted brands for classic cars and trucks. We offer many applications of headers and LS swap headers for fitment and long-lasting performance. With our commitment to excellence and customer satisfaction, you can rely on CPP to provide the best components for your vehicle restoration and enhancement projects.
