The Cummins 03-07 EGR Exhaust Manifold is a high-quality and heat-tolerant bended steel product that is made in the U.S.A. This exhaust manifold offers numerous benefits, including increased fuel mileage by .2 to .3 miles per gallon and increased horsepower by 28 to 32. Its ceramic coating reduces heat and improves air velocity, resulting in lower manifold temperatures and reduced EGT's. With no cracking, leaking, or warping, this exhaust manifold improves gasket life and provides greater strength and durability. Its joints are designed with tighter tolerances and 50% more surface contact to ensure no leaks. Additionally, it eliminates sharp turns and twists, creating smooth airflow to the turbo.
