The Flowmaster® Force II Cat-Back Exhaust System is engineered for Ford Super Duty owners who want enhanced performance and a deep, refined exhaust tone without excessive interior drone. Designed as Flowmaster’s quietest performance series, the Force II delivers a noticeable increase in sound and power while maintaining comfortable cabin acoustics during cruising.

This bolt-on, emissions-legal system features full stainless steel construction and utilizes the factory hanger locations for a straightforward installation. A high-flow 50 Series HD™ performance muffler with large 4.00-inch internals feeds dual 3.00-inch mandrel-bent tailpipes, giving you the option of either dual rear exits under the bumper or dual side exits behind the rear tires—ideal for towing to prevent exhaust blow on trailers or boats.
