With the top down you don’t always need a loud exhaust, our ROUSH Active exhaust system puts you in control of your Mustang’s exhaust note. Stealthily pull out of your driveway without waking the kids by keeping your Active exhaust in touring mode. Switch to SPORT mode and open up your exhaust once you hit the open road. Using our ROUSH Quad Tip exhaust with mandrel bent T-304 stainless steel from the axle back and a high flow dual tip muffler as a base our proprietary Active Exhaust system uses data from your Mustang’s Powertrain control module, positioning its valves based on throttle position, RPM and speed. A brushed aluminum, console mounted, selector switch swaps sound modes on the fly. And our Active Exhaust app for iOS lets you create and edit sound maps for custom mode.

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

TOURING mode keeps the volume of your exhaust as quiet as possible. The exhaust valves stay closed all the time.

SPORT mode opens up under acceleration while keeping the exhaust quiet during normal driving conditions. Accelerator position RPM and vehicle speed are used to determine valve position.

TRACK mode has the valves wide-open the whole time without restricting your Mustang’s raw sound. This mode is intended for track use and is not legal for street use.

CUSTOM mode lets you create and edit custom sound maps with the ROUSH Active Exhaust iOS app. Using the app gives you control over the position of the valves based on vehicle speed, rpm and accelerator position.
