Improving the Performance of Your 5.9L Dodge Cummins Engine
Upgrading your diesel truck’s stock exhaust to an MBRP performance exhaust can add up to 18 horsepower with 28 ft/lb more torque. The 4” T409 stainless steel, mandrel bent tubing used for this Down-Pipe Back Kit opens up the flow path allowing your engine to remove the hot air fast. The spiral-louvered high flow muffler was specifically designed to give your 5.9L Cummins truck a rich, mellow sound.
Built for Easy Installation
Using all the factory mounts and OEM hangers, the Turn Down Series Down-Pipe Back Kit is a bolt-on exhaust unit. The estimated project time is 1.5-2 hours and that includes removing your stock exhaust. This kit is designed to fit any 2003 and 2004 Dodge Ram with a 5.9L Cummins engine. MBRP includes all the clamps and parts you need for easy installation whether your diesel truck has a Crew Cab, Extended Cab, short or long bed.
