Replace The Weakest Link Before It Breaks

If you're putting your RAM 2500 or 3500 through its paces, your stock exhaust manifold is probably already showing signs of stress. The BD Diesel 1045969 Exhaust Manifold is the upgrade your 6.7L Cummins has been waiting for. Whether you’re hauling trailers, climbing grades, or sitting in long idle sessions, the factory manifold just can’t take the heat forever. This heavy-duty replacement is built to handle what the original couldn’t, with a thick-wall cast design and a slip-joint center section that expands and contracts without cracking under pressure. It bolts directly in place with zero modifications, making it a simple solution that adds serious durability to your engine bay. You’ll also get cleaner turbo response and smoother performance thanks to its pulse-divided flow design. For truck owners who depend on their rig every day, this is the kind of upgrade that pays off mile after mile.

Designed To Survive Heat Cycles And Heavy Loads

The BD Diesel 1045969 Exhaust Manifold was engineered to solve a common failure point on 2019-2024 RAM 2500 and 3500 pickups with the 6.7L Cummins. Unlike the one-piece OEM design that often cracks from repeated heat cycles, this manifold uses a two-piece slip-joint that allows natural thermal expansion without stressing the casting. The thick-wall construction offers increased durability in high-temperature conditions, which is critical for trucks that tow, haul, or run performance tunes. It also features a divided pulse design that keeps exhaust pulses isolated, improving exhaust flow and helping your turbo spool more efficiently. The result is smoother throttle response and less lag, especially under load. BD includes turbo and EGR studs to ensure a secure, leak-free fit, and the pre-drilled EGT port makes it easy to install temperature gauges. This manifold is fully emissions compliant under EPA regulations and is a direct replacement that retains all factory EGR components. It delivers serious reliability and performance without the need for tuning or custom fabrication.
