This BD Diesel Exhaust Manifold Kit is designed for RAM 3500, 4500, and 5500 Cab & Chassis trucks equipped with the 6.7L Cummins engine (2019–2024). It replaces the factory one-piece manifold with a thick-wall, two-piece design that allows natural expansion and contraction during heat cycles, dramatically reducing the risk of cracking. Ideal for both stock and modified applications, this manifold improves turbo spool, drivability, and long-term reliability.
