In it, we get an advanced look – or more rather, a listen – at the forthcoming exhaust system’s tunable bellow. We presume that, like Roush’s active, quad-tip exhaust for the S550 Ford Mustang GT, this kit will give users the ability to control an internal valve with a smartphone to adjust the exhaust volume, and craft custom programs to adjust the valve in real-time as vehicle speed and throttle position change.
One of those Mustang exhaust systems costs $2,689.99 on the Roush Performance website; pricing for this Focus RS active exhaust hasn’t yet been announced, but it ought to be somewhere in the same ballpark. Currently, Roush’s web store offers no performance upgrades for the 2016-’17 Ford Focus RS. On that, firms like Mountune and Hennessey have got enthusiasts pretty well-covered.
