The DPS 3 piece exhaust manifold, is an all new mold design for just the 24 Cummins manifolds.
This is an important factor, because nearly every other competitor manifold on the market uses the same mold design for the 24v Cummins Manifold (round port), as for the 12 valve (rectangular port) manifolds and then they machine the ports to the correct shape.
This is good for production cost, but poor for exhaust flow and performance, because the competitors mold design is smaller and then machined to shape, leaving smaller ports and poor exhaust transition, compared to our new design.
Our 24V Cummins exhaust manifold round port manifold a separate mold.
More costly to make? Yes. Better performance for you? Absolutely! Still the best price manifold on the market, why even consider anything else?
The Diesel Power Source 3-Piece 24 valve Cummins manifold for the Dodge Cummins engine is both a great performance manifold and a factory Cummins replacement manifold.
This 3-Piece Manifold is cast from Ductile Iron similar to your turbine housing (which can handle extreme heat, without much expansion or shrinkage).
We’ve designed this manifold with CFD testing to increase turbo spool-up, and increase exhaust gas efficiency, all while maintaining exhaust gas velocity, so the turbo will function optimally.
We’ve made our Cummins exhaust manifold the end ports flow more similar to the center ports so the end ports EGT’s won’t be severely hotter than the center ports.
Some competitors 24 Valve Cummins Exhaust Manifold boast “Huge runners, or Huge tube design”, while this sounds appealing, too big of runners will actually slow the exhaust velocity, and then need to re-accelerate as it bottle necks through the turbo, causing a loss in horsepower, and spool-up.
We have actually seen a competitors manifold decrease horsepower by 40 hp on a 400 hp truck, where our manifold will typically cause a 10-18HP gain.
Stock manifolds and one-piece competitor manifolds are known to shrink significantly, causing manifold-cracking, gasket problems, and exhaust flow problems created by exhaust port misalignment.
Even stainless steel manifolds will shrink significantly, causing misalignment.
The dirty little secret is that competitors stainless steel actually moves (expands and contracts) more than ductile iron does.
Our 3-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.
