ROUSH 2015-2017 Ford Mustang ACTIVE Exhaust Upgrade Kit (Requires ACTIVE-READY Exhuast Kit)

Convert your ROUSH Quad Tip exhaust to a full Active exhaust and take control of your Exhaust note. Our Active Exhaust upgrade kit makes any ROUSH passive quad-tip exhaust into an active exhaust that allows you to ?tune? your exhaust note using our iOS application for virtually infinite sound possibilities. The system utilizes an easily installed valve system that adjusts the flow of the exhaust, thereby adjusting tone and volume. ?Plug and play? Installation requires no cutting or welding. Included in the kit is a 4 mode selector knob with faceplate so you easily switch to pre-set and custom modes on the fly. 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
