Roush Mustang 2.3L Ecoboost Quad Tip Active Exhaust Kit (COUPE ONLY)

*image is only a representation and may not be accurate

A Loud exhaust isn’t always better, with ROUSH Active exhaust systems you are in control of your Mustang’s Voice. Want to pull out of your driveway without waking the neighbors? Keep your Active exhaust in touring mode to stealthily get on the road. Then switch over to sport to open up your exhaust and have some fun. Our ROUSH Quad Tip exhaust is mandrel bent T-304 stainless steel from the axle back, leading to a high flow dual tip muffler fitted with our proprietary Active Exhaust system. ROUSH Active exhaust uses data from your Mustang’s OBDII, positioning its valves based on throttle position, RPM and speed. A console mounted, brushed aluminum selector switch swaps sound modes on the fly. And our Active Exhaust app for iOS gives you full control over the sound maps for custom mode.

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.
