Durable, High-Flow Manifold for Performance and Longevity

The BD Diesel 1045968 Exhaust Manifold is designed for 2013–2018 Dodge RAM 2500–5500 6.7L Cummins Cab & Chassis trucks and is engineered to outperform and outlast the restrictive OEM manifold. Crafted from high-silicon ductile iron, this fully divided pulse manifold can withstand extreme heat cycles, including those caused by DPF regeneration and high-performance tuning, while maintaining structural integrity over the long haul.

With larger internal porting, the manifold supports improved airflow for increased horsepower and torque, while lowering drive pressure for enhanced turbo response and efficiency. The precision-engineered slip joint allows for expansion and contraction under heat, helping to reduce cyclic thermal fatigue and prevent common cracking or warping issues found in OEM castings.

Ideal for both stock and modified engines, this manifold is pre-drilled for pyrometer probes, making it tuning- and monitor-ready. Whether you're working your truck hard daily or adding power, this manifold gives you performance, reliability, and peace of mind.
