BD DIESEL 1045987 PULSE 5.9L CUMMINS EXHAUST MANIFOLD – DODGE RAM 2003–2007 2500/3500

Product Description

The BD DIESEL 1045987 Pulse Exhaust Manifold is the proven solution for cracked factory manifolds on 2003–2007 Dodge Ram 2500/3500 trucks with the 5.9L Cummins. Built as a perfect stock-location replacement, this fully divided pulse manifold improves durability, prevents exhaust leaks, and supports better turbo response by maintaining exhaust energy to the turbine.

BD Diesel 1045987 pulse exhaust manifold, 5.9 Cummins exhaust manifold upgrade, 03-07 Dodge Ram manifold replacement, divided pulse manifold, high silicon ductile iron manifold, slip joint exhaust manifold, pyrometer probe port, prevent cracked manifold

Unlike the factory one-piece design that commonly cracks under high heat cycles, the BD Pulse Manifold uses a two-piece, high-silicon ductile iron casting with precision slip joints to allow controlled expansion and contraction. This reduces cyclic thermal fatigue that causes cracks and warped sealing surfaces. The manifold is also pre-drilled for a pyrometer probe for clean EGT gauge installations.
