BD Diesel Cast Exhaust Manifold – Part # 1045967

The BD Diesel 1045967 cast exhaust manifold is engineered for heavy-duty diesel trucks, specifically fitting 2007-2009 Dodge Ram 3500 models. Crafted from high-silicon ductile iron, this manifold is designed to withstand extreme temperature cycling caused by DPF regeneration and high-performance operation. Its robust construction ensures durability and resistance to cracking under demanding conditions, making it an ideal replacement for stock manifolds on both stock and performance trucks.
The manifold features an optimized pulse flow design, created using advanced modeling software to reduce turbo spool times and drive pressures. This results in quicker turbo response and increased overall power output. The larger porting design accommodates higher horsepower applications, providing additional airflow capacity for increased performance. The thick-walled casting combined with an integral slip joint allows for thermal expansion and contraction, greatly extending the manifold’s service life and preventing leaks or cracks.
Pre-drilled for pyrometer probes, the BD Diesel cast exhaust manifold is fully EGR compatible, ensuring compliance with emissions systems and vehicle diagnostics. Gasket, bolt, and spacer kits are sold separately, giving flexibility for installation and customization. The open throttle outlet flange outperforms the stock manifold by providing a smoother, more efficient flow path, enhancing engine responsiveness and power.
Designed for use with the Holset HE351 turbo, this manifold is suitable for high-performance applications where durability and thermal management are critical. Its larger porting design ensures it can handle any increase in power, making it a reliable upgrade for fleet and performance trucks. Overall, the BD Diesel 1045967 exhaust manifold offers a significant performance boost and long-term reliability for heavy-duty diesel engines.
