The aFe BladeRunner ported ductile iron exhaust manifold for 1998.5–2002 Dodge Ram Cummins 5.9L addresses common factory manifold cracking with a thicker 0.25 in. wall. Precision-ported flanges, matched ports and merged runners reduce backpressure and improve exhaust flow, reportedly outflowing the factory manifold by 50% to help turbo spool and throttle response. Dual 1/8 in. NPT ports and gaskets/hardware are supplied for installation.
