BD Diesel Exhaust Manifold Kit

2013–2018 Ram 3500 6.7L Diesel

Part #: 1046068

Overview

The BD Diesel Exhaust Manifold Kit is engineered specifically for the 2013–2018 Ram 3500 equipped with the 6.7L Cummins diesel engine. This high-quality exhaust manifold kit is designed to replace the factory manifold with a durable, fully divided pulse manifold that enhances exhaust flow and reliability under demanding conditions. Ideal for diesel truck owners seeking improved durability and longevity, this kit offers a direct-fit solution that maintains OEM compatibility while providing superior thermal resistance and vibration tolerance.

Built to withstand the extreme heat and stress typical of heavy-duty diesel applications, the BD Diesel manifold kit ensures consistent performance and reduces the risk of manifold cracking or failure. It is an excellent upgrade for fleet operators, off-road enthusiasts, and anyone who relies on their Ram 3500 for heavy towing or commercial use.

Key Features

This exhaust manifold kit incorporates advanced design and materials to deliver lasting performance and value. Key features include:

• Fully divided pulse manifold design for optimized exhaust scavenging and reduced backpressure
• Constructed from high-silicon ductile iron to resist extreme temperatures and vibration
• Precision slip joints that allow for thermal expansion and contraction, minimizing cyclic fatigue
• Enhanced durability to extend manifold service life under heavy-duty conditions
• Complete kit includes new gaskets, bolts, and spacers for a hassle-free installation
• Direct bolt-on fitment for 2013–2018 Ram 3500 6.7L diesel engines
• Engineered to maintain OEM exhaust routing and compatibility with factory components

Construction & Design

The BD Diesel Exhaust Manifold Kit 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 intense temperatures generated by the 6.7L Cummins engine without warping or failure.

Its fully divided pulse design improves exhaust gas flow by separating exhaust pulses, which helps reduce turbulence and backpressure. The inclusion of precision slip joints allows the manifold to expand and contract naturally with engine heat cycles, significantly reducing the risk of thermal fatigue and extending the overall lifespan of the manifold.

Installation & Fitment

The BD Diesel Exhaust Manifold Kit is designed for straightforward installation on 2013–2018 Ram 3500 trucks with the 6.7L diesel engine. It is a direct replacement for the factory manifold, requiring no modifications to the exhaust system or engine components. The kit includes all necessary gaskets, bolts, and spacers, ensuring a complete installation package that saves time and effort.

Professional installation is recommended to ensure proper torque specifications and sealing, but experienced DIYers with the right tools can also perform the upgrade with confidence.

What's Included

• BD Diesel fully divided pulse exhaust manifold
