Cummins inline-6 engines are notorious for cracking their long, one-piece cast-iron manifolds, a problem that still affects many RAM trucks. BD Diesel's exhaust manifold solves this with a thick-wall casting and slip-joint center section, allowing natural expansion and contraction to greatly reduce the risk of cracks.
Key details
- Its divided Pulse Manifold design optimizes exhaust flow by harnessing the engine's natural exhaust pulses for smoother operation and drivability.
- Fully emissions-compliant, the manifold also comes pre-drilled with an EGT probe port for easy monitoring.
- Whether your truck is stock or modified, this is the perfect upgrade for reliability and durability.
- Available as a standalone manifold (PN:1045970) or as a complete installation kit including new bolts, spacers, and gaskets.
