4-Inch Cat-Back Single-Exit Exhaust System

The Banks Power Monster Exhaust System (48701-B) is a 4-inch, single-exit, cat-back exhaust designed for specific Dodge Ram trucks. Constructed from 100% stainless steel with heavy-wall tubing, this system aims to significantly improve exhaust flow. This reduction in restriction contributes to improved horsepower, enhanced throttle response, and potentially better fuel economy. This specific system is designed for the 2004-2007 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins 325hp engine and featuring a Crew Cab Long Bed (CCLB) configuration. It is a direct bolt-on replacement for the factory exhaust system.
