The BD Diesel 1045987 Exhaust Pulse Manifold is designed as a direct drop-in replacement for 2003-2007 Dodge Ram 2500 and 3500 trucks equipped with 5.9L engines. Constructed from high-silicon ductile iron, this fully divided pulse manifold withstands extreme temperatures and vibration conditions common in heavy-duty diesel applications. Its modern engineering ensures optimal internal geometry, while precision slip joints allow for expansion and contraction, significantly reducing cyclic thermal fatigue and extending manifold longevity. This design feature minimizes the risk of cracking or exhaust leaks, providing a reliable solution for both stock and performance upgrades.
The manifold includes stainless steel hardware, ensuring durability and corrosion resistance during installation. Pre-drilled ports allow for easy installation of pyrometer probes, enabling accurate exhaust temperature monitoring essential for tuning and diagnostics. The BD Diesel pulse manifold is compliant with EPA standards and is carb-acknowledged, making it suitable for a variety of fleet and off-road applications. Replacing OEM Cummins part numbers 3967995, 3943871, and 3943875, this product offers a robust upgrade for heavy-duty diesel engines seeking increased thermal capacity and durability.
Designed to prevent cracking and exhaust leaks, the manifold enhances overall engine performance and reliability. Its high-silicon ductile iron construction ensures resilience under severe operating conditions, while the fully divided design promotes efficient exhaust pulse flow. Whether for maintenance or performance enhancement, this manifold provides a long-lasting, high-quality solution for heavy-duty diesel trucks, supporting improved engine efficiency and longevity.
