Suited For Everyday Driving
Flowmaster's Force II Exhaust Systems for passenger cars are perfect for adding that Flowmaster level of performance tone enhancement, but are concerned about an exhaust system that is too aggressive for daily driving. These quieter sounding systems are mandrel bent for maximum performance and include specially selected mufflers to deliver a mild exterior and interior tone.
