BD Diesel Pulse Exhaust Manifold for 2003-2007 Dodge Ram 2500/3500 (5.9L) - 1045987

Fits 2003-2007 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins engine.

The BD Diesel Pulse Exhaust Manifold is a performance-grade replacement for the factory unit, engineered to solve the common cracking and exhaust leak issues found in stock manifolds. Cast from high-silicon ductile iron, this manifold is built to withstand extreme thermal cycles and heavy-duty use. The fully divided pulse design optimizes internal geometry, improving exhaust flow to the turbocharger for better throttle response and overall efficiency.

To ensure long-term reliability, this manifold features precision-machined slip joints. These joints allow the casting to expand and contract freely during operation, significantly reducing the cyclic thermal fatigue that leads to structural failure. The manifold comes pre-drilled and tapped for pyrometer (EGT) probes, simplifying the installation of monitoring equipment.
