Construction & Design

The manifold is crafted from high-silicon ductile iron, a material known for its excellent thermal stability and resistance to cracking under high heat cycles. This robust construction ensures the manifold can endure the harsh operating environment of diesel engines without warping or failure.

BD Diesel utilized advanced computer-aided design and flow modeling to optimize the internal geometry of the manifold. This precision engineering enhances exhaust gas pulse flow, which helps the turbocharger spool faster and more efficiently, contributing to improved engine responsiveness and power output.

Additionally, the inclusion of precision slip joints allows the manifold to expand and contract naturally with temperature changes. This feature significantly reduces thermal fatigue, extending the service life of the manifold and maintaining a reliable seal over time.

Installation & Fitment

The BD Diesel Cast Exhaust Manifold is designed as a direct replacement for the factory manifold on compatible Dodge Ram 3500 models. Installation typically requires no modifications, making it a straightforward upgrade for experienced mechanics and DIY enthusiasts alike.

It fits the following vehicles:

• 2007 Dodge Ram 3500 5.9L Diesel
• 2008–2010 Dodge Ram 3500 6.7L Diesel
• 2011–2012 Dodge Ram 3500 6.7L Diesel
