BD Diesel Pulse Exhaust Manifold - 1998-2002 Dodge Ram 2500/3500 (5.9L) 1045947

Fits 1998-2002 Dodge Ram 2500 and 3500 (5.9L).

The BD Diesel Pulse Exhaust Manifold is a heavy-duty drop-in replacement designed to eliminate the common cracking and leaking issues found in factory units. Cast from high-silicon ductile iron, this manifold is engineered to withstand extreme exhaust gas temperatures and vibration. Its fully divided pulse design optimizes internal geometry, improving exhaust flow and turbocharger spool-up compared to standard cast manifolds.

To solve the problem of cyclic thermal fatigue, this manifold features precision-machined slip joints. These joints allow the manifold to expand and contract freely during heat cycles, preventing the stress-induced cracking that often plagues one-piece designs. This manifold comes pre-drilled and tapped for pyrometer probes, making it ready for EGT sensor installation.
