BD Diesel Pulse Exhaust Manifold for 1989-1998 Dodge D/W 250/350 and Ram 2500/3500 (5.9L) 1045948

Fits 1989-1993 Dodge D250, D350, W250, W350 and 1994-1998 Dodge Ram 2500/3500 (5.9L).

The BD Diesel Pulse Exhaust Manifold (MPN 1045948) is a heavy-duty replacement for the factory exhaust manifold, engineered to solve common cracking and warping issues. This fully divided pulse manifold is cast from high-silicon ductile iron, a material specifically chosen for its ability to maintain structural integrity under the extreme temperatures and vibrations found in performance and towing applications.

Using modern internal geometry, this manifold optimizes exhaust flow to the turbocharger. The precision-machined slip joints are a critical feature, allowing the manifold to expand and contract during heat cycles without stressing the casting. This significantly reduces thermal fatigue, preventing the common exhaust leaks and cracks associated with OE units.
