Diamond Eye Manufacturing 510217 Performance Exhaust System 2004.5-2007 Dodge 5.9L Cummins

The Diamond Eye Manufacturing 510217 is a performance exhaust system engineered specifically for 2004.5 to early 2007 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine. Designed to fit all cab and bed length configurations, this kit delivers improved exhaust flow, reduced backpressure, and a noticeable boost in turbo efficiency — all critical factors for diesel performance and longevity.

Diamond Eye exhaust components are manufactured using CNC mandrel bending technology, which ensures smooth, consistent bends throughout the entire exhaust path. Mandrel bending preserves the full inner diameter of the tube at every bend, eliminating the flow restrictions common in crush-bent pipes. Tubing is available in both aluminized and stainless steel construction for durability and corrosion resistance.
