Features and Benefits:
- Designed for the 2016-2018 Focus RS
- Enhances Engine Power and Torque
- Sound Volume Adjustable Varex Rear Muffler
- Smartbox control module with GEO, Matrix, and Manual mode

The Varex muffler can go from stock-level quiet to throaty and aggressive. An included Varex Smart Box provides user-adjustable sound levels. Using its "Manual mode," you can select the 5 pre-set valve positions, Closed, 25%, 50%, 75% and Fully Open.

Another mode, "Matrix mode," will allow the Smartbox to control the exhaust valve based on real time information from your car via OBD2 port. Another feature included with Smart Box is the “GEO” function. Using the smartphone app, users can define a region on a map, and then set a particular exhaust sound for that location: perfect for quiet neighborhoods.

4" black tips deliver an exceptional sound, unmatched performance, and an athletic appearance. These premium-quality exhaust kits are fully polished and treated to resist corrosion. They're built to last and look great too! Thanks to a bolt-on design, these kits are a simple performance upgrade for your RS.
