Hedman Stepped Hedders

Aftermarket headers outperform the standard, factory-built cast iron exhaust manifolds that come with your vehicle. This is due to the least amount of materials and effort to get appropriate performance at manageable cost. In the end, performance suffers because of back pressure. Exhaust gases are not pulled as efficiently from the chambers. When new gas is pumped back into the manifold, the mix of old and new forms a pressure differential that drains power from the engines. For race car drivers, decreased power was a losing proposition. To increase racing speed and performance, Hedman developed its line of headers to allow exhaust gases to escape more efficiently, a process that is known as scavenging, using increased force and suction. The result was cooler air temperatures, better airflow, and the ability for cars to operate at peak efficiency with improved horsepower. The tube diameter increases to a maximum 1 5/8 inches as it moves from the combustion chamber to the ends, thereby increasing the scavenging effect. The specialties of the Stepped Hedder include downshifts and passing. In dynamometer tests, cars consistently experienced “Torque Boosts” with significantly improved RPM rates. If you’re happy with leisurely diving, stick with the standard OEM part. If you want power and performance, upgrade to the Hedman Stepped Hedder.
