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. We make the best exhaust manifold dodge cummins 5.9 diesel, Cummins replacement manifolds.

The DPS manifold, is an all new mold design for just the 12 Valve Cummins exhaust manifold. This is an important factor, because nearly every other competitor manifold on the market uses the same mold design for the 24 valve (round port), as for the 12 valve manifolds (rectangular port) 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 competiting mold design is smaller and then machined to shape, leaving smaller ports and poor exhaust transition, compared to our new design. Our 12V 2nd Gen Cummins manifold has a separate rectangular port mold. More costly to make? Yes. Better performance for you? Absolutely! Still the best price 5.9 Cummins exhaust manifold on the market, why even consider anything else.
