Eliminate the costly exhaust manifold cracks prevalent in the factory exhaust manifold. The aFe BladeRunner exhaust manifold for the popular 98.5-02 5.9L Dodge Ram Cummins (24V) sets a new standard. In recent testing, this exhaust manifold outflowed the factory exhaust manifold by 50% improving performance and throttle response. The thick wall (0.25in. vs. 0.15in.) design increases strength eliminating warping and cracking. The matched ports and a merged runner design reduces exhaust backpressure, maximizing exhaust flow. Once you install this awesome exhaust manifold, you will feel improved turbo spool up times, improved throttle response and increased performance.
