Doug's Headers - High Temperature Coated
Designed SPECIFICALLY for the GMC MOTORHOME to produce Low End Torque. Comes with oxygen sensor ports.
Headers greatly reduce engine temperature by more efficiently drawing the exhaust gasses out. Lowering the temperature of the cylinder and the combustion chamber creates a denser fuel charge and therefor allows your engine to create more power.
Ceramic coating is a high luster silver color that will not discolor with the introduction of heat and is more resistant to corrosion and heat at even higher temperatures. It creates a thermal barrier which lowers the understood temperature and adds life to your headers. The approximate dimensions of the package is 36hx20wx16L
