• Improves manifold longevity compared to factory components

Construction & Design

The BD Diesel Exhaust Manifold Kit is crafted from high-silicon ductile iron, a material known for its exceptional strength and thermal resistance. This choice of material ensures the manifold can endure the high heat cycles and mechanical stresses generated by heavy-duty diesel engines without cracking or deforming.

The manifold features precision-engineered slip joints that allow for controlled expansion and contraction during engine operation. This design innovation significantly reduces thermal fatigue, a common cause of manifold failure, thereby extending the service life of the component. The fully divided pulse design also helps maintain optimal exhaust pulse timing, contributing to efficient engine breathing.

Installation & Fitment

This exhaust manifold kit is designed for direct replacement of the factory manifold on Dodge Ram 2500 and 3500 trucks with 5.9L and 6.7L diesel engines from 2007 to 2018. Installation is straightforward with no modifications required, making it suitable for professional mechanics and experienced DIYers alike. The kit includes all necessary gaskets, bolts, and spacers to ensure a secure and leak-free fitment.

What's Included

• BD Diesel fully divided pulse exhaust manifold
• New exhaust manifold gaskets
• All required mounting bolts
• Spacers for proper alignment and fitment

Ideal For

This manifold kit is perfect for Dodge Ram owners who demand durability and reliability from their diesel exhaust systems. It is especially suited for those who operate their trucks under heavy loads, tow frequently, or drive in harsh conditions where factory manifolds may fail prematurely. Additionally, it is an excellent choice for restoration projects or performance upgrades aiming to maintain OEM-level fitment with enhanced longevity.

BD Diesel Performance designs and manufactures diesel performance parts aimed at stronger power delivery, improved reliability, and heavy-duty capability. Their lineup spans turbo and fueling upgrades, manifolds, intercoolers, and other supporting components—built for Cummins, Power Stroke, and Duramax owners who want more torque for towing, work, or competition.
