Based on our ROUSH Quad Tip axle back exhaust with high flow dual tip mufflers, corrosion resistant T-304 stainless steel and high flow mandrel bends, our proprietary Active Exhaust system uses servo controlled valves to control your exhaust note. The included console mounted selector switch has a brushed aluminum finish and seamlessly switches between 4 different preset and custom modes. Our active Exhaust app for iOS lets you create your own sound profile for custom mode.

The ROUSH Active Exhaust system features four modes: TOURING, SPORT, TRACK, and CUSTOM.

TOURING mode with the exhaust valves closed all the way, keeps the exhaust volume to an absolute minimum.

SPORT mode is quiet during normal driving conditions and more aggressive under acceleration. Accelerator position and vehicle speed are used to determine valve position for a more aggressive sound.

TRACK mode keeps the exhaust valves fully open with no restriction to the raw sound of your Mustang. This mode is not legal for street use and is intended for track only.

CUSTOM mode gives you the power to create a custom sound map with our iOS application, personalizing the exhaust tone to fit your lifestyle. The ROUSH active exhaust app gives you full control over valve position based on rpm, vehicle speed and accelerator position.
