Exhaust Manifolds for Diesel Trucks - Dodge, Ford, GM

Performance exhaust manifolds are designed to lower the amount of back pressure or flow resistance and increase a vehicle's power output.

Why You Should Purchase Exhaust Manifolds from OCDiesel:

A single tube, known as a collector is where the tubular manifolds exhaust gathers, lowering back pressure and providing an engine with a greater amount of power to put out. There are also headers that do not have collectors, which are usually called zoomie headers. Performance or aftermarket headers are typically designed with mild or stainless steel tubes accompanied by flat flanges and sometimes a larger collector. A few are finished with a ceramic composite material or painted with heat resistant finish. Some manifolds are insulated in order to lower the intake temperature.
