BD Diesel 1045967 Pulse Flow Cast Exhaust Manifold - Select 2007-2012 Dodge/Ram 3500 (6.7L)

Fits select 2007-2012 Dodge and Ram 3500 (6.7L) trucks.

This BD Diesel pulse manifold is engineered from high-silicon ductile iron to withstand the extreme thermal cycling common during DPF regeneration. Designed with advanced modeling software, the pulse flow geometry optimizes exhaust gas delivery to the turbocharger for quicker spool times, lower drive pressures, and an overall increase in performance. It serves as a durable performance replacement for the stock 6.7L Cummins manifold when used with the Holset HE351 turbo.

To solve the common issue of manifold cracking and exhaust leaks, BD Diesel utilizes a thick-walled casting and precision-machined slip joints. These joints allow the manifold to expand and contract freely during heat cycles, significantly reducing thermal fatigue and extending component longevity. The open throat outlet flange design further improves flow over the factory unit, supporting increased power levels without restriction.
