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.

Free shipping to the lower 48 states. When shipping to anywhere outside of the lower 48 states, additional shipping fees may apply.

**All DPS replacement 1st gen Cummins Manifold & 2nd gen cummins manifolds have been granted an exemption by CARB, which means our 1st gen & Second Gen Cummins manifolds are legal to be installed and used in the state of California.

Our manifold replaces 12V 5.9 Cummins exhaust manifold & 12v cummins exhaust manifold, in Dodge Cummins 12V vehicles.

    This Manifold has done what is says. Turned up 12V 362 turbo injectors and AFC mods on a 5 Speed. Lowered EGT by 75 degrees and spools at around 1550 Rpms about 200 Rpms faster than the stock Manifold. Easy to install Nice coating and welded between flanges all in a 3 piece. Sure will last for a long time. Truck runs smoother and doesn't feel laggy at all had to remove some pre boost to tone her down a bit. Thanks DPS just what I needed .

    sounds like new truck at 305k...mine shrank badly on ends, does make my 66mm turbo sing 2-300 rpms earlier and the top end it loud n pulls hard but also has light pedal power too
