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.

RAM Billet Steel Flywheels

Cast flywheels are not explosion-proof and can be dangerous when used in high performance applications at higher rpm. RAM billet steel flywheels are recommended as replacements for factory-cast flywheels in high performance and racing vehicles. Made in America and produced in-house, all RAM flywheels are computer balanced within a 1/2 oz., surface ground (which results an optimum mating surface), and are ready to run out of the box. They're better for launching heavier drag race cars and provide better drivability in street vehicles. SFI-approved, RAM billet steel flywheels are CNC-machined from certified materials. Order the model recommended for your year/make and engine application. Technical note: As they spin, heavy flywheels store more energy than lighter ones. Engine and gearing combinations that require more power or inertia to make the car launch without bogging the motor need heavier flywheels. However, heavier flywheels accelerate slower. Lighter flywheels create less inertia at launch, but accelerate quicker through the gears. When choosing a flywheel, you must consider the car's weight, operating rpm of the engine, and, most importantly, the gearing. Insufficient gearing will cause an engine with too light of a flywheel to "bog" on launch.

Cometic MLS Head Gaskets

Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load—resulting in less bore distortion. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.
