1990-1993 5.9L Dodge Cummins
Finally, a 4" exhaust kit for the first generation Cummins! The kit starts as a 3" downpipe and then enlarages to a 4" from downpipe to tailpipe, and includes a flow-through muffler for a great sound. Also included in the kit are all necessary clamps. Simply choose whether your truck is intercooled versus non-intercooled from the two options below, and you're on your way! To really finish this exhaust off, add one of our many exhaust tips for a stylish accent!
Note: Intercooled models have a built in heat shield on the down pipe.
