Say Goodbye To Cracked Manifolds For Good

If you're still running the stock manifold on your 6.7L Cummins, there's a good chance it's already showing signs of fatigue. BD Diesel’s 1046069 Exhaust Manifold Kit is built to handle what the factory part couldn’t. Whether you're towing, daily driving, or tuned for more power, this is a serious upgrade in both durability and performance. The thick-wall casting and two-piece slip joint design help the manifold absorb extreme heat without cracking or warping over time. That means fewer headaches and better peace of mind for truck owners who put their rigs to work. It bolts right into place using the factory location and comes with all the gaskets and hardware you need for a smooth install. No special tuning required, no tricky fitment issues, just reliable, long-term performance. For anyone looking to bulletproof their exhaust system, this manifold kit is a no-brainer.

Engineered For Heat Flow And Long Term Strength

The BD Diesel 1046069 manifold is a purpose-built upgrade designed to outlast and outperform the OEM design on 2019-2024 RAM 2500 and 3500 pickup trucks. It starts with a heavy-duty cast iron construction that uses a thick-wall design to handle extreme exhaust temperatures without failing under pressure. The center slip joint allows the manifold to expand and contract naturally during heat cycles, which significantly reduces stress points that often lead to cracking. BD’s divided pulse flow design keeps exhaust pulses separated to improve turbo spool-up and maintain consistent backpressure. This results in a more responsive throttle and smoother overall drivability, especially when towing or running modified tuning. The manifold is fully compatible with the stock EGR system and comes pre-drilled with an EGT probe port for those running gauges. Installation is straightforward and requires no permanent modifications, making this kit an ideal replacement for both stock and mildly upgraded builds. With EPA compliance and SEMA certification, it delivers proven reliability that holds up over the long haul.
