BD Diesel 03-07 Dodge Exhaust Manifolds


SKU BDD1045987 Categories , , , ,


The BD Diesel Exhaust Manifold is a must-have for anyone with a 2003-2007 Dodge Cummins 5.9L engine. This high-quality exhaust manifold is cast from high-silicon ductile iron, which makes it extremely durable and resistant to cracks and exhaust leaks. The Pulse exhaust manifold features expansion joints that allow it to expand and contract without cracking or causing exhaust leaks.

The “pulse-tuned” design of this manifold is specifically engineered to assist in combustion chamber evacuation and increase exhaust flow. This results in quicker turbo spool-up, reduced backpressure, increased power, and better fuel economy. Some kits include stainless steel fasteners and washers to prevent lost or loose manifold bolts, and gaskets are available separately.

The three-piece pulse manifold for the Dodge Cummins application is designed to increase exhaust gas efficiency and help spool up the turbocharger sooner with less exhaust back pressure. This design eliminates the problems that persist with the stock manifold in both 12 and 24-valve engines, such as shrinking and breaking of the manifolds. The stock manifolds can shrink as much as 3/8 inches, which can cause manifold cracking, gasket problems, and exhaust flow problems created by exhaust port misalignment.

The three-piece pulse manifold is a cast of a much higher-grade material than the stock manifold, which can handle far more heat without being brittle. The manifold comes with new socket head cap screws and a washer.
