Hedman Hedders increase performance and economy by improving the efficiency of a car's engine. Hedders remove exhaust gases faster and more efficiently than stock manifolds. Stock manifolds are designed for low cost, and have a short restrictive design which causes some exhaust gas to get bottled up in the cylinder. Because of these residual exhaust gases in the cylinder, the size of the new fuel charge is limited and engine temperature increases. Hedman Hedders have smoothly contoured individual pipes for each cylinder. These primary pipes create a suction effect, called scavenging, which pulls the exhaust gases out. This creates additional velocity in the cylinder and helps pull in the fresh fuel charge. Hedders were originally developed for racing applications and Hedman Hedders are carefully designed to provide the maximum increase in power for passing, hauling loads, towing, etc. In some cases this extra power contributes to improved economy because the engine does not have to work as hard to pull a heavy load or conquer a steep grade.
