The aFe BladeRunner ductile iron exhaust manifold for 2003–2007 Dodge Ram 5.9L Cummins replaces the factory manifold with a thicker flange and merged runner design to reduce backpressure. In testing it outflowed the factory unit by 23%, yielding quicker turbo spool and improved throttle response. The manifold includes EGT ports, ported flanges, and hardware to address cracking issues common to stock manifolds.
