Product Description
Upgrade your 12-valve Cummins with the BD DIESEL 1046048 Pulse Exhaust Manifold Kit, a heavy-duty, multi-piece manifold engineered to replace the failure-prone factory casting on 1988–1998 Dodge 5.9L Cummins 12-Valve trucks. This divided pulse manifold improves exhaust flow, reduces the chance of cracking, and helps maintain consistent turbo response under towing, hauling, and daily driving conditions.
This kit is cast from high-silicon ductile iron to withstand extreme exhaust temperatures and vibration. The multi-piece design includes precision slip joints that allow controlled expansion and contraction, reducing cyclic thermal fatigue that commonly cracks one-piece manifolds. For a complete drop-in installation, the kit includes new exhaust port gaskets, turbo mount gasket, high-strength fasteners, and spacers.
