Upgrade your 2004.5–2007 Dodge Ram 2500/3500 5.9L Cummins with this high-performance DPF delete pipe, available in both 4-inch and 5-inch options. This pipe replaces your factory Diesel Particulate Filter (DPF), eliminating restriction, lowering exhaust temperatures, and improving both horsepower and fuel economy.
