- Direct fitment for multiple Dodge Ram 2500 and 3500 models from 2007 to 2018
- Improves manifold longevity by reducing stress caused by thermal cycling
- Compatible with both diesel and gasoline-powered engines within specified model years
Construction & Design
This exhaust manifold is crafted from high-silicon ductile iron, a material chosen for its excellent thermal stability and resistance to cracking under high heat and vibration. The fully divided pulse design separates exhaust pulses to improve scavenging and reduce interference between cylinders, which helps maintain consistent exhaust flow and engine efficiency.
Precision-engineered slip joints allow the manifold to expand and contract naturally with temperature changes, significantly reducing the risk of thermal fatigue and extending the service life of the manifold. This thoughtful design ensures reliable operation even under the most demanding conditions encountered by heavy-duty trucks.
Installation & Fitment
The BD Diesel Cast Exhaust Manifold is a direct replacement part designed to fit a wide range of Dodge Ram 2500 and 3500 models equipped with 5.7L Hemi, 6.4L 392, 5.9L Diesel, and 6.7L Cummins diesel engines from 2007 to 2018. Installation requires no modifications, making it a straightforward upgrade or replacement for your factory manifold.
Professional installation is recommended to ensure proper torque specifications and gasket sealing, which are critical for optimal performance and leak-free operation.
What’s Included
- BD Diesel Cast Exhaust Manifold
