Fitment
03-07 5.9L Dodge Ram Cummins ISB
In recent testing, this high-flow exhaust manifold outflowed the factory exhaust manifold by up to 25%, improving overall performance. The thick wall (0.25″ vs. 0.15″) T3 flange design increases strength; eliminating warping and cracking, a common problem with factory exhaust manifolds. Matched ports and a merged runner design reduce exhaust backpressure, maximizing exhaust flow.
Once you install this awesome exhaust manifold, you will feel shorter turbo spool-up times and a better throttle response.
