AFE 46-40011 BladeRunner Stainless Exhaust Manifold 03-07 Dodge 5.9L Cummins

Eliminate the costly exhaust manifold cracks prevalent in the factory Cummins exhaust manifold. The aFe BladeRunner exhaust manifold for the popular 5.9L Dodge Cummins is constructed out of cast 304 stainless steel with a reinforcing rib for strength.

The BladeRunner exhaust manifold produces an air flow increase of 23% over the stock manifold. This manifold also features 2 EGT probe ports, thick wall design for increased strength (0.25" vs 0.15" for the stock unit), matched ports and has a merged runner design to maximize exhaust flow. This manifold will also improve turbo spool up times which improve overall performance and throttle response.
