Features Include:

  • Flows 24% more than the industrial manifold
  • Cools rear ports by up to 200 degrees
  • T3 Turbo Exhaust Flange
  • Excellent exhaust flow characteristics lower EGT’s, improves overall performance.
  • Drilled/Tapped ports for pyrometer and pressure fitting.
  • Black High Temperature Coating
  • Comes pressed together, pressure tested and ready to install.
  • Expansion joints prevent cracking

5.9 Cummins Motorhome Manifold Includes:

  • All necessary bolts and hardware

  • 6 Steel Gaskets

  • Turbo Flange Gasket

Stock manifolds are known to shrink significantly, causing manifold-cracking, gasket problems, and exhaust flow problems created by exhaust port misalignment. The Diesel Power Source 2-Piece 12 valve 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.

The 2-Piece Manifold vastly improves exhaust flow allowing better fuel efficiency, quicker turbo spool-up, increasing overall horsepower and torque, and cooling the end cylinders much better. It also has a divided scroll design to improve spool-up.

This exhaust manifold is generally used on RV's Buses, and Fummins (Ford Cummins Conversions). 

Replaces and fits:

  • 5.9 Cummins industrial exhaust manifold
  • 5.9 Cummins motorhome
  • 12 valve Cummins bus engine
  • 12V Cummins bus

FAQ's 

Q:  I have a 5.9 cummins industrial exhaust manifold, how is the DPS RV exhaust manifold better for my Cummins motorhome?

A:  The DPS 5.9 Cummins Motorhome manifold cools the rear cylinders by 150-200 degrees and flows much better than the factory 5.9 cummins industrial exhaust manifold.  It is CFD designed and tested to outflow all other 12 valve industrial manifolds.
