aFe BladeRunner Exhaust Manifold for 2003-2007 Dodge Ram 2500/3500 (L6-5.9L / 5.9L) 46-40011

Fits 2003-2007 Dodge Ram 2500 and 3500 trucks (L6-5.9L / 5.9L).

The aFe Power BladeRunner exhaust manifold replaces the failure-prone factory manifold with a heavy-duty, high-performance solution. Engineered to solve the common issue of cracking and warping in stock units, this manifold is constructed from cast 304 stainless steel. It features an ultra-thick 0.25" wall design and a reinforcing rib along the flange for maximum structural integrity under high heat and pressure.

Beyond durability, the BladeRunner manifold utilizes matched ports and a merged runner design to optimize exhaust gas velocity. This results in a 23% increase in flow over the factory manifold, leading to faster turbo spool-up, improved throttle response, and reduced exhaust backpressure. For those monitoring performance, two integrated EGT (exhaust gas temperature) probe ports are included for easy gauge installation.

• Construction: Cast 304 stainless steel for superior heat and corrosion resistance
• Performance: Outflows factory manifold by 23% for better efficiency
• Durability: Thick 0.25" walls (vs. 0.15" stock) prevent warping and cracks
• Design: Merged runner and matched port design optimizes flow path
