BD Diesel Manifold Exhaust Pulse - 2003-2007 Dodge 5.9L

If you're working on your 2003-2007 Dodge 5.9L Cummins, replacing a cracked or leaking exhaust manifold is a common task. This BD Diesel Pulse Exhaust Manifold is built to handle the tough conditions these trucks often face, whether they're stock or modified.

This manifold is made from high-silicon ductile iron, a material chosen for its ability to stand up to extreme heat and constant vibration without cracking. It features a fully divided pulse design, which helps manage exhaust pulses more effectively and reduces the stress that can lead to leaks. The precision slip joints are a smart touch; they allow the manifold to expand and contract with temperature changes. This reduces cyclic thermal fatigue, a major cause of manifold failure, and significantly extends its service life compared to a standard manifold. It's also pre-drilled to accept pyrometer probes, making it easier to monitor your exhaust gas temperatures, especially if you've upgraded your engine's performance.

While this manifold is a direct replacement for Cummins part numbers 3967995, 3943871, and 3943875, keep in mind that gaskets, bolts, and spacers are sold separately. This is a solid option for anyone looking for a more durable exhaust manifold for their 5.9L Cummins.
