DPS-5.9-CUMM-EXHMAN-3G 5.9 CUMMINS 3RD GEN EXHAUST MANIFOLD 2003-2007

The DPS-5.9-CUMM-EXHMAN-3G 5.9 Cummins 3rd Gen Exhaust Manifold 2003-2007 from Diesel Power Source is the ultimate aftermarket solution for your 5.9 Cummins engine. Designed to fit Dodge Ram 2500 and 3500 trucks, this performance manifold offers superior flow and durability compared to stock manifolds.

Crafted from high nickel ductile iron, this 2-piece design includes expansion joints that allow for natural expansion and contraction with heat, eliminating common issues such as warping, cracking, and exhaust flow problems. The manifold has been meticulously engineered using Computational Fluid Dynamic (CFD) Testing to optimize turbo spool-up and enhance exhaust gas efficiency.

With a T3 flange stock fit, this exhaust manifold outperforms the factory Cummins manifold by flowing 23% more, resulting in increased balanced exhaust flow and turbo spool-up velocity. It effectively lowers Exhaust Gas Temperatures (EGTs) on the rear cylinders by up to 200 degrees, promoting better engine performance and longevity.

Every detail has been carefully considered in the design of this manifold, from the black high-temperature coating to the inclusion of block gaskets and bolts for easy installation. The manifold also features drilled and tapped ports for pyrometer and pressure fitting, ensuring compatibility with a wide range of accessories.

Unlike single-piece stainless steel manifolds that are prone to excessive movement and potential damage, the DPS 5.9 Cummins Exhaust Manifold offers a reliable and efficient solution for your 5.9 Cummins engine. Take your vehicle's performance to the next level with this premium aftermarket exhaust manifold from Diesel Power Source.
