98.5+ Dodge 5.9L Cummins BladeRunner Ductile Iron Exhaust Manifold

Please note! This manifold is a center dump manifold and is designed to replace the factory exhaust manifold on 1998.5-2002 5.9L Cummins trucks. It can be used on trucks as new as 2018, however, since 2003-2018 trucks have an offset turbo flange and in 6.7L applications has a different turbo flange altogether, it is NOT a direct replacement for these trucks. 


• Outflows the factory exhaust manifold by 50%, improving performance and throttle response
• Ported flanges ensure excellent seal and clean stylish look.
