Product Description

The aFe Power 46-40054 BladeRunner Exhaust Manifold is a high-flow performance upgrade engineered for RAM 2500 and 3500 heavy-duty trucks equipped with the 6.7-liter Cummins inline-6 diesel engine from 2007½ through 2015. Designed to replace the restrictive factory manifold, this ported BladeRunner unit significantly improves exhaust flow, which can contribute to quicker turbo spool-up, reduced backpressure, and stronger throttle response.

Constructed from robust cast ductile iron with reinforced wall flanges, the manifold provides long-lasting durability under demanding thermal conditions. Machined ports and merged runner design optimize exhaust gas movement, while dual 1/8" NPT ports allow the addition of exhaust gas temperature monitoring for tuning and diagnostics. This manifold includes a full set of 6-port gaskets and installs using existing factory mounting points, offering a straightforward bolt-on solution for diesel owners seeking enhanced performance and reliability without sacrificing OEM compatibility.
