Touring Mode: Exhaust valves closed all the way. Keeps the exhaust volume at a neighbor-friendly note.
Sport Mode: 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.
Please Note: This exhaust is for 2018-2021 models only. It will not fit 2015-2017 models regardless of installed valance.
Tech Tip: Installation requires cutting of the factory exhaust piping. Once the modifications have been made to the factory exhaust system, installation is a simple bolt-in procedure.
