aFe 46-40012 5.9L Cummins BladeRunner Ductile Iron Exhaust Manifold

The aFe BladeRunner Exhaust Manifold for the popular 03-07 Dodge RAM Cummins with the 5.9L turbo diesel engine sets a new standard in manifold design. In recent testing, this exhaust manifold outflowed the factory exhaust manifold by up to 23%, improving performance and throttle response. The thick wall (0.25″ vs. 0.15″) T3 flange design increases strength, eliminating warping and cracking prevalent in the factory exhaust manifolds. The matched ports and merged runner design reduce exhaust backpressure, maximizing exhaust flow. Once you install this awesome exhaust manifold, you will feel quicker turbo spool-up times, improved throttle response, and increased performance.

1-Piece Construction:
This manifold is constructed of durable cast ductile iron with a reinforcing rib for maximum strength between the port flanges.

Dual Auxiliary Ports:
2 exhaust gas temperature (EGT) probe ports are supplied for easy installation of gauges or testing equipment.
