The Diesel Power Source 5.9 Cummins Exhaust Manifold for the Dodge Cummins CR engine is the best exhaust manifold Dodge Cummins 5.9 diesel replacement on the market. DPS 2-Piece Manifold is cast from high nickel ductile iron (which can handle extreme heat without). We've designed this manifold based on Computational Fluid Dynamic (CFD) Testing, which will results in quicker turbo spool-up, and increases exhaust gas efficiency.

Stock manifolds are known to shrink significantly, causing manifold-cracking, gasket problems, and exhaust flow problems created by exhaust port misalignment. Our 2 Piece Manifold, on the other hand, allows manifold to expand and contract with heat, eliminating warping and cracking to the manifold, eliminating the dreaded manifold shrinkage.

This manifold flows much better than the factory Cummins Manifold. Our manifold lowers EGTs on the rear cylinders by 200 degrees.

Features Include:

  • Flows 23% more than the stock manifold.
  • Flow tested and balanced for increased balanced exhaust flow, while maintaining velocity for increased turbo spool up.
  • Keeps rear cylinders up to 200 degrees cooler
  • Includes block gaskets, and two bolts.
  • Drilled/Tapped ports for pyrometer and pressure fitting.
  • Made from Moly-Bendum Ductile Iron.
  • Black High Temperature Coating
  • Comes pressed together, pressure tested and ready to install
  • 5.9 cummins performance exhaust manifold

Don't make the mistake of a single piece stainless exhaust manifold. Stainless steel manifolds move (expand and contract), 2 times more than our manifold. So while the stainless manifold may not break, your head, bolts and gasket will.
