BD Diesel BD Diesel Cast Exhaust Manifold - 07.5-12 Ram

When you're working on your 2007-2010 Dodge Ram 3500, especially if you're looking to get more out of that 6.7L Cummins engine, this cast exhaust manifold from BD Diesel is a solid choice. It's designed as a direct replacement for stock, but with construction that can handle more. This manifold is made from high-silicon ductile iron, a material chosen specifically to stand up to the intense heat and vibrations that come with diesel exhaust, particularly during DPF regeneration cycles. It's built to last, reducing the chances of cracks and leaks that can plague factory manifolds.

BD Diesel engineered this manifold using advanced modeling software to optimize the flow of exhaust pulses. This means quicker turbo spool-up, which translates to more responsive power and lower drive pressures. The design features precision slip joints that allow the manifold to expand and contract with temperature changes. This is a key feature that greatly reduces thermal fatigue, a common cause of cracking in exhaust components, ultimately increasing the manifold's longevity. The porting is larger than many other options, ready to handle increased power levels, and the open throttle outlet flange outperforms the stock unit. It's also pre-drilled for pyrometer probes, making it easier to monitor your exhaust gas temperatures.

While this manifold is designed to be a performance upgrade, it's also fully EGR compatible. Keep in mind that gaskets, bolts, and spacer kits are available separately, so you'll want to plan for those when ordering. This manifold is not CARB approved and cannot be shipped to California.
