Roush 2015 Mustang GT Quad Tip Active Exhaust Kit (COUPE ONLY)

With a ROUSH Quad Tip Active Exhaust system you are in total control of the volume and performance of your ROUSH Mustang. Pull into your driveway at night without waking the neighbors; turn down your exhaust to avoid unwanted attention or open up the pipes all the way for the ultimate performance V8 sound. This system is 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 ties in with your Mustang’s powertrain control module, letting the valves open based on throttle position. Use the included console mounted selector switch to swap sound modes on the fly and fine tune your custom mode with our Active Exhaust app for iOS.

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

TOURING mode can be selected to close the exhaust tailpipe valves completely and keep the exhaust volume at its absolute minimum – especially useful when you want to fly under the radar without waking up the neighbors.

SPORT mode allows the exhaust valves to open when the engine is idling and close during normal, non-aggressive driving. The valves open again when you step on it or drive at high speeds. These settings are pre-loaded to be more aggressive (louder) than stock, but are still legal for street operation. When the engine is running, the accelerator pedal position and vehicle speed are used to determine the position of the Active Exhaust valves.

TRACK mode is the loudest of the modes. This mode keeps the Active Exhaust valves fully open at all times when the engine is running and is typically used only on the track, as it is not legal for street operation.

CUSTOM mode allows the operator to employ an iOS application and Wi-Fi module attached to the vehicle’s diagnostic port to personalize the exhaust sound for unique calibration. Through the application, the user gains full control over the position of the valves based on vehicle speed and accelerator position.
