The Force II® system is designed to replace the original factory mufflers located behind the rear axle using factory style connections. With easy fit in mind, these stainless steel systems are mandrel-bent for maximum performance, feature specially-engineered 80 Series™ mufflers that have a deep moderate performance tone outside the car, with little to no interior resonance in the cab. The system uses the factory hangers and are finished off with quad 3.00-inch polished 304 stainless steel tips. Includes all necessary parts, hardware and instructions for a quick and easy installation. Force II systems are suited to customers looking for efficiency improvements without a lot of noise. Like all Flowmaster® systems, the benefits include improved throttle response, power and mileage.
