Unlock the full soundtrack and performance potential of your 5.0 V8 Mustang GT with the Xforce VAREX 3″ Cat-Back Exhaust System. Designed specifically for the 2015–2017 S550 fastback, this premium 304-grade stainless steel system delivers sharper throttle response, improved flow and a proper V8 tone that brings the Coyote engine to life.
Valved Exhaust – Control Your Sound Anytime
At the heart of this system are Xforce’s VAREX valved mufflers. These electronically controlled valves allow you to switch between quiet, refined operation and a deep, aggressive V8 roar whenever you want.
Valves Closed: Neighbour-friendly, near-OEM volume for early starts and long journeys.
Valves Open: Straight-through flow and a proper Mustang soundtrack with real presence.
Optional SmartBox: Add Bluetooth control, automatic valve maps, geo-fencing and preset profiles for the ultimate flexibility.
It’s the best of both worlds – loud when you want it, subtle when you need it.
