304 Stainless Steel Cat-Back Exhaust System

The Cobb Tuning cat-back exhaust system is designed as a direct replacement for the 2016-2018 Ford Focus RS. The tubing is CNC mandrel-bent to provide optimal exhaust flow. The dual polished 4.5-inch double-wall slash-cut tips add a stylish finishing touch to the rear of the vehicle. A key feature is the integration of the OEM exhaust valve, which allows for plug-and-play installation without needing to transfer the stock unit. This valve is controllable via the car's drive modes, working seamlessly with COBB's Off-The-Shelf (OTS) maps or custom Pro-Tunes. This exhaust offers a dual personality: it provides an aggressive, race-car-like sound with the exhaust valve open, while maintaining OEM-level convenience and noise reduction when the valve is closed. Beyond the sound, the increased flow capacity is ready to support significant power increases, offering substantial performance potential alongside an enhanced auditory experience. The system is compatible with both stock and COBB downpipes.
