BD Diesel 1046087 Pulse Exhaust Manifold Kit for 2003-2007 Dodge Ram 2500/3500 (5.9L)

Fits 2003-2007 Dodge Ram 2500 and 3500 (5.9L). This BD Diesel Pulse Exhaust Manifold is a heavy-duty replacement for the factory unit, engineered to solve the common issue of manifold cracking and exhaust leaks in Cummins applications.

Cast from high-silicon ductile iron, this manifold is built to withstand extreme exhaust gas temperatures (EGTs) and intense vibrations. The fully divided pulse design optimizes internal geometry for better turbocharger response and efficiency. To handle the rigors of heavy towing and performance use, it features precision-machined slip joints that allow the manifold to expand and contract during heat cycles. This design significantly reduces cyclic thermal fatigue, preventing the stress cracks that plague OE castings.

The kit is a comprehensive solution, including high-strength Grade 10.9 black oxide-coated hardware and necessary gaskets to ensure a reliable seal at the head and turbo flange. The manifold also comes pre-drilled for pyrometer probes, making it ready for EGT gauge installation.
