BD Diesel 07.5-12 Dodge 3500/4500/5500 Cab & Chassis 6.7L Cummins Exhaust Manifold Kit

Already running a tuner or other upgrades on your 6.7L Cummins? This exhaust manifold kit from BD Diesel is the next piece of the puzzle for getting the most out of your engine. It's specifically designed for the 2007-2010 Dodge Ram 3500, and also fits the 2011-2012 Ram 3500/4500/5500 Cab & Chassis models. This isn't just a stock replacement; it's built to handle the extra heat and stress that comes with a modified diesel engine.

What sets this manifold apart is its construction from high-silicon ductile iron. This material is chosen because it can withstand the extreme temperature cycling that happens during DPF regeneration cycles, which can crack lesser manifolds. The design incorporates precision slip joints that allow the manifold to expand and contract with heat changes. This reduces thermal fatigue, a common cause of cracks and exhaust leaks in factory manifolds, greatly increasing its longevity. You'll also find it comes with everything you need for a smooth installation: new gaskets for the EGR port, exhaust port, and turbo mount, along with grade 10.9 black oxide-coated bolts and spacers.

This manifold is also pre-drilled for pyrometer probes, making it easy to add a temperature gauge to monitor your exhaust gas temperatures. It's fully EGR-compatible, so you don't have to worry about bypassing emissions systems. While it's a solid upgrade for performance, please note that it is not CARB approved and cannot be shipped to California.
