aFe BladeRunner Exhaust Manifold for 2003-2007 Dodge Cummins (46-40012)

Product Description

The aFe BladeRunner exhaust manifold for the popular 03-07 Dodge Ram Cummins with the L6-5.9L (td) 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 reduces 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. One-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: Two Exhaust Gas Temperature (EGT) probe ports are supplied for easy installation of gauges or testing equipment. Hassle-Free Installation: All necessary hardware is included for a hassle-free installation. Note: Does not include gaskets. Emissions Disclaimer: Some or all of the applications listed are 50-state exempt, CARB EO# D-550-39.
