BD Diesel 19-24 Ram 3500/4500/5500 C&C 6.7L Cummins Exhaust Manifold

This exhaust manifold from BD Diesel is built from thick, 1/2-inch cast iron, a material chosen for its ability to handle the intense heat and pressure generated by the 6.7L Cummins engine in your 2019-2024 Ram 3500, 4500, or 5500 Chassis Cab. Stock manifolds can sometimes crack under these conditions, leading to exhaust leaks and reduced performance. This heavy-duty replacement is designed to be a strong, reliable upgrade that can stand up to the demands of a hardworking truck.

BD Diesel uses a unique, multi-piece design for this manifold. This approach allows for better expansion and contraction as the engine heats up and cools down, which helps prevent the cracking issues common with one-piece factory units. The thicker cast iron also contributes to its durability and helps manage heat more effectively. This isn't just a replacement part; it's a well-built component intended to outlast the original equipment and maintain consistent exhaust flow, which is crucial for engine efficiency and power delivery, especially under load.

When installing this manifold, you'll want to ensure you have all the necessary gaskets and hardware. While this manifold is designed to fit your specific Ram truck, it's always a good idea to consult the manufacturer's installation instructions for the best results and to confirm any additional components you might need for a complete and leak-free installation. Please note that this part is not CARB approved and cannot be shipped to California.
