Summit Racing™ Headers

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.)

Summit Racing™ Metallic-Ceramic Coated Headers

They improve performance, keep heat contained, look fantastic, and have a sweet Summit Racing™ price--they're Summit Racing™ metallic-ceramic coated headers! These headers are meticulously crafted with high-quality steel tubing to remove exhaust gases with maximum efficiency and minimal power loss. Cyclical welds eliminate distortion, while heavy-duty 5/16 in. machined flanges eliminate leaks. Finishing these Summit Racing™ headers is a polished, metallic-ceramic thermal barrier coating, which not only extends service life by controlling underhood temperatures and fighting thermal fatigue and corrosion, but it also looks absolutely awesome! Factory header paint lasts a few minutes and just can't compare to the longevity of these Summit Racing™ metallic-ceramic coated headers. These headers are designed for off-road and racing use only, unless otherwise noted, and include gaskets, mounting hardware, and collectors. Gain performance and looks under the hood with Summit Racing™ metallic-ceramic coated headers.

Flowtech Headers

Flowtech headers are designed to provide optimum exhaust flow for increased horsepower, torque, fuel economy, and improved throttle response. Leak-tested for maximum performance, they feature the industry's best welds for durability and are carefully engineered for precise fit. Available for a wide range of applications, they're offered in block hugger, competition, fenderwell, lakester, long tube, mid-length, shorty, upright, and turbo styles. Varying with the application, Flowtech headers are constructed from sturdy and lightweight cold-rolled mild steel or stainless steel for increased strength and durability. All tubing is mandrel-bent to provide consistent tubing diameter for smooth flow and increased exhaust velocity. Extra-thick, machined header flanges provide a leak-free seal and maximum strength. For long-term rust and corrosion-resistance, available finishes include natural and polished stainless steel, high heat-resistant black paint, or a satin silver metallic ceramic thermal barrier coating. All mounting hardware and premium gaskets are included. Important notes: Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Hooker recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage. Flowtech does not recommend the use of header wraps as this will void the warranty.

Mr. Gasket Header Bolts

Installing headers can sometimes be a real pain, due to the tight spaces and the location and shape of the tubes. Mr. Gasket can help make installation a little easier and also help prevent annoying exhaust leaks from under-tightened header bolts. They have both the socket-head and hex-head styles of header bolts available. Hex types are heat-treated Grade 5 steel and have smaller-than-standard heads to ease access in tight spaces. Socket-head bolts are made from stronger Grade 8 steel for added ruggedness and they're great for those really difficult-to-reach spots. Both styles have a protective black oxide finish.
