Hear The Roush Stage 3 Mustang’s Active Exhaust Modes: Video

Sponsored Links

Once upon a time, if one wanted a car with a loud, invigorating exhaust note, that meant that he or she had to put up with its voluminous bellow even in everyday driving situations, which can become irritating. Conversely, if said person wanted a tame, quiet exhaust sound for everyday driving, the car couldn’t be made magically louder for maximum satisfaction during spirited driving.

And then, at some point, a few bright people figured out that exhaust systems could be designed with integrated valves for on-the-fly auditory adjustment.

Roush Performance makes such an exhaust system for the current-generation Ford Mustang, which can be ordered as a standalone kit, or optioned as part of a full Roush Stage 1, 2, or 3 Mustang build. The Stage 3 model – a ballistic, supercharged GT with some 670 horsepower – is what the folks at Roush Performance elected to use to demonstrate their Active Quad Exhaust System in the above video. Each of the system’s three pre-programmed modes is used here, giving us a good look at what to expect from the Touring, Sport, and Track settings.

Of course, there is also a “Custom” option which isn’t demonstrated here. It allows the user to come up with his or her own Mustang exhaust program, tying the valve position to the vehicle speed and throttle position.
