aFe Power BladeRunner Ductile Iron Exhaust Manifold with EGR for 2007-2018 Dodge/Ram 2500/3500 (L6-6.7L)

Fits select 2007-2018 Dodge and Ram 2500/3500 trucks (L6-6.7L).

The aFe Power BladeRunner ductile iron exhaust manifold (MPN 46-40054) is engineered to replace the prone-to-warping factory manifold on your 6.7L Cummins. Constructed with a thick-wall design and merged runner geometry, this manifold significantly reduces exhaust backpressure and increases flow by 49% over the stock unit. This improved flow helps lower exhaust gas temperatures (EGTs) and enhances throttle response for better overall drivability.

• Thick-wall ductile iron construction eliminates warping and cracking common in factory manifolds
• Machined ports and merged runner design reduces exhaust backpressure and turbulence
• Dual 1/8 inch NPT ports included for easy installation of EGT gauges or sensors
• Cast-in EGR flanges allow for full retention of the factory EGR system
• Outflows the factory manifold by up to 49% for improved turbo spool and efficiency
• Includes six port gaskets for a complete, leak-free installation
• Direct bolt-on replacement for factory hardware
