Show original supplier description
The X Force ES-FST16-VMK-CBS is a cat-back exhaust system specifically designed to enhance the sound and performance of the Ford Focus ST models from 2012 to 2019 (LW and LZ variants). Constructed from durable 304-grade stainless steel with tig-welded seams, this system is built for longevity and resistance to corrosion. The centerpiece of this system is the patented Varex valved muffler, which allows for adjustable sound volume. Owners can switch between a quieter, more subdued tone for everyday driving and an aggressive, loud exhaust note for spirited driving, all controlled via key fobs. The system features 3-inch mandrel-bent pipework that leads to dual 2.5-inch tubing, culminating in 5-inch double-walled tips. All required gaskets, bolts, and nuts are included to facilitate a complete installation. Note that for 2013 and 2014 models, the unused left rear sway bar hanger will need to be removed to ensure proper fitment. For an even more advanced level of control, an optional SmartBox can be added. This accessory integrates with a patented Bluetooth smartphone app, offering features such as pre-set automatic valve control and geo-fencing, allowing for a truly customizable exhaust experience.
