This exhaust system is perfect for Dodge 2500/3500 Cummins 2WD owners from 1989 to 1993. If you live in a dry area with little precipitation or you're on a budget but still want great performance and sound, this is for you. It can be used during daily commuting, long - distance driving, or when you just want to show off your vehicle's power. The tubing is made of heavy - gauge Aluminized Steel, and it's mandrel bent for maximum exhaust flow.
