Product Description

BD Diesel's 1046070 exhaust manifold kit replaces the factory one-piece manifold on 2019-2024 Ram 3500/4500/5500 Cab & Chassis trucks with the 6.7L Cummins - an engine known for cracking its long, stock cast-iron manifold over time. The thick-wall ductile iron casting and two-piece slip-joint design are built to absorb heat expansion without the fatigue that plagues the OEM part.

Beyond added durability, the divided pulse design improves turbo response and throttle feel, and a pre-drilled EGT port makes temperature monitoring straightforward. It's a direct bolt-on using the factory mounting location, with all gaskets and hardware included - a solid upgrade for owners who tow, work, or tune their truck and want to get ahead of a known failure point. Not legal for sale on California-licensed vehicles.
