DPS | High Flow 6.7 Exhaust Manifold | Best 6.7 Cummins Exhaust Manifold Upgrade | T4

The Diesel Power Source best 6.7 Cummins Exhaust Manifold for the Dodge Cummins is the best 6.7 Cummins exhaust manifold upgrade, because it helps turbos spool up sooner with less exhaust back pressure.

T-4 FLANGE WILL NOT FIT FACTORY TURBO!

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

DPS 6.7 Exhaust Manifold Features Include:

Flow Charisteristics

• • Computational Fluid Dynamic design (we know how it flows)
  • Improved Exhaust Flow
  • Flows 33% more than the stock manifold
  • Lowers exhaust drive pressure / back-pressure

Fitment

• T4 Flange size (will not fit factory turbo)
• Fits T4 S400 Turbos
• Puts Turbos in factory location
• Includes 6 new gaskets, and two bolts.
• Drilled/Tapped ports, two sizes, for pyrometer and pressure fitting.
• Made with high nickel content for excellent heat performance.
• Black High Temperature Coating
• Comes pressed together, pressure tested and ready to install
• Has EGR / Emissions ports
• 2-Piece Design won’t crack like single piece manifolds

Fluid Dynamic Testing Matters:

DPS 6.7 exhaust manifold offers improved exhaust velocity competitors, because it’s not just port size, it’s balance, size and design of ports which affect this.

We have the best 6.7 Cummins exhaust manifolds because our CFD testing allows us to actually trace the air molecules through the system so we know how.

2-Piece Design Matters:

DPS 2-Piece Manifold can handle extreme heat without cracking, because of both the materials and 2-piece design.

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.

For T4 S400 turbo owners wanting to keep your turbo in the factory location DPS 6.7 Cummins exhaust manifold upgrade is the best flowing of all aftermarket manifolds this is one of the best best 6.7 cummins upgrades.

Diesel Power Source 6.7 exhaust manifold has the EGR ports, for both emissions compatibility or for external wastegate setups.

The best 6.7 Cummins aftermarket exhaust manifold, spools turbo faster and flows more air than a Steed speed 6.7 cummins manifold.

If you’re looking for 6.7 cummins aftermarket exhaust manifold for an S300 or S400 turbo, this is a perfect choice for the best 6.7 cummins upgrades.

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.

Flows exhaust like a 6.7 Cummins header.
