2003 - 2007 Dodge 5.9L 24V Cummins
Part # 1045987
This Pulse Flow Exhaust Manifold can be used as a direct replacement for Cummins part numbers 3967995, 3943871 & 3943875 used on pick-up, motor homes, industrial and commercial engines.
BD’s New Pulse Exhaust Manifold Stops Cracks in their Tracks! You can replace the single stock exhaust manifold casting with this 2-piece design. These high performance manifolds are tuned and flowed for higher exhaust volumes and temperatures. They feature heat expansion joints and a strong design that will support the weight of twin turbochargers if needed.
Horsepower creates heat—pure and simple. On a high-output engine like the Dodge-Cummins, high exhaust gas temperature (EGT) is enough to cause the stock exhaust manifold to crack. BD’s new Pulse manifold for ’88-02 applications (two-piece offset Pulse available for ’03-06 applications) is cast from high-silicon ductile iron which can withstand extremely high temperatures, as well as the additional weight created by bigger single or twin turbo systems. Two expansion joints allow the manifold to expand and contract without cracking or exhaust leaks.
Of course, the Pulse wouldn’t be a BD product if it didn’t offer the benefit of improved performance. As its name would suggest, this manifold is pulse-tuned for more efficient combustion chamber evacuation and higher exhaust flow. The result is quicker turbo spool-up, reduced backpressure, more power and better fuel economy.
All Pulse flow exhaust manifold kits come assembled and are complete with hardened steel turbo mount studs to resolve the issue of loose or lost fasteners (Manifold bolts & gasket kits available separately).
