BD Diesel 1045970 Exhaust Manifold RAM Cab Chassis Cummins - 3500/4500/5500 6.7L 2019-2024

The BD Diesel 1045970 is a high-performance exhaust manifold designed specifically for 2019-2024 RAM 3500/4500/5500 Cab & Chassis trucks equipped with 6.7L Cummins engines. Cummins inline-6 engines are notorious for cracking their long, one-piece cast-iron manifolds, and BD Diesel's exhaust manifold solves this problem with a thick-wall casting and slip-joint center section, allowing natural expansion and contraction to greatly reduce the risk of cracks.

Key Features:

• Cast from high-silicon ductile iron which can withstand extremely high temperatures
• Expansion joint allows the manifold to expand and contract without cracking or creating exhaust leaks
• Open throat outlet flange outperforms the stock manifold
• Pulse-tuned design for more efficient combustion chamber evacuation and higher exhaust flow
• Designed to bolt directly in place of the factory manifold with EGR cooler compatibility
• Ready for pyrometer probes with pre-drilled holes

This upgraded manifold addresses the high exhaust gas temperatures that cause stock manifolds to crack, especially during regeneration cycles caused by factory emissions systems. Experience quick spool times and low drive pressures with an overall increase in performance.

Important Note: Not for sale on licensed California vehicles. Gaskets, bolts, and spacers sold separately.
