| 2004.5-2007 | Dodge/Ram | Cummins 5.9L |
Give your 5.9L Cummins the breathing room it deserves. The DDC-4D05M replaces your restrictive factory exhaust with a high-flow, 4″ mandrel-bent system designed specifically for the 2004.5-2007 Ram. This kit includes a high-flow performance muffler, providing that iconic Cummins grunt while keeping EGTs in check and performance at its peak.
At Dirty Diesel, we prioritize fitment. This system comes complete with contour-bent hangers and reinforced flanges to ensure a “one-and-done” installation. Whether you’re towing or cruising, you’ll notice improved throttle sensitivity and better mileage across the board.
Note: This kit is designed for turbos featuring the larger turbo collar. If you have a smaller turbo collar (typically found on early 2003-2004 models), click here.
