BD Pulse Exhaust Manifold - 5.9 Cummins 2003-2007

3rd Gen Common Rail BD 1045987 Exhaust Manifold

This 3rd Gen manifold upgrade features a heavy-duty multi-piece design to eliminate manifold cracks. The single piece design of the factory exhaust manifold is prone to cracks which causes exhaust leaks that can rob you of power. The BD-Power Exhaust Pulse Manifold is cast from high silicon ductile iron, and features an expansion joint to allow the manifold to expand and contract without cracking. As the name would imply, these manifolds are "pulse tuned" to assist in combustion chamber evacuation and increased exhaust flow. The result is quicker turbo spool-up, reduced backpressure, increased power, and better fuel economy. Great for stock, and performance applications. Pre-drilled and tapped for pyrometer probe.
