Our Active Exhaust application for iOS allows you to 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 at a neighbor-friendly note. 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 use 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.
