Take control of your Mustang's exhaust note, and enjoy that V8 rumble any way you desire. With dual high-flow mufflers, corrosion-resistant T-304 stainless steel and high-flow mandrel bends, our patented ROUSH Active Exhaust system uses electronically controlled valves to control your exhaust note and make your Mustang stand out from the crowd. The included console-mounted selector switch has a brushed aluminum finish, and seamlessly switches between four different preset and custom modes. Our Active Exhaust application for iOS allows you to create your own sound profile for custom mode.
