aFe BladeRunner Exhaust Manifolds for 1998-2002 RAM 2500, RAM 3500 - 46-40034

The aFe BladeRunner exhaust manifold set replaces the factory cast-iron manifolds on 1998-2002 RAM 2500 and 3500 trucks equipped with the 5.9L Cummins diesel. The reinforced one-piece 304 stainless steel design eliminates the crack-prone weak points inherent in OEM manifolds. Benefits include faster turbo spool-up reduced exhaust gas temperatures by 100-200°F and measurable throttle response gains under load. The BladeRunner is a direct upgrade for diesel owners pushing higher boost levels.

Each manifold incorporates a merged runner layout with matched ports to maximize exhaust flow velocity. The 304 stainless steel construction handles high EGTs without corrosion while reinforced ribs between each exhaust port add structural rigidity where factory manifolds typically fail. Two EGT probe ports are included for monitoring exhaust temperatures. The thick-wall casting dampens exhaust pulse resonance for a cleaner diesel idle. Expect spool improvements of 300-500 rpm versus stock manifolds.

Direct bolt-on replacement using factory turbo and exhaust connections. All mounting hardware is included. A high-temperature gasket set is recommended during installation. Compatible with aftermarket turbo upgrades and up-pipe modifications. Professional installation is recommended for torque sequence adherence. Retorque after the first heat cycle to ensure a lasting seal under high EGT operation.
