aFe Mach Force XP 4" Stainless Exhaust Kit for 2003-04 Dodge 5.9L Cummins TrucksThe aFe Mach Force XP DPF-Delete Exhaust Kit eliminates the use of the restrictive diesel particulate filter (DPF) and increases the performance of your diesel truck. This exhaust kit is made from 4" mandrel bent stainless steel pipes that flow into a 24" long muffler, but also included is a muffler delete pipe. The 4" pipes allow the 5.9L diesel engine to breathe more than the stock exhaust leading to an increase in horsepower and torque while lowering EGTs. aFe designed this kit for fast and easy installations on all 2003 and 2004 5.9L Dodge Ram 2500/3500 Cummins diesel trucks by using OE style bayonet hangers that connect to the factory mounting locations and band clamps for a leak-free seal.
