Description
The Flowmaster Outlaw Cat-Back Exhaust System is engineered specifically for 2013–2018 Ford Focus ST models equipped with the 2.0L turbocharged engine, delivering an extremely aggressive exhaust tone for drivers who want maximum sound and performance. This system is designed for enthusiasts who want both aggressive exterior and interior sound levels and are not afraid to stand out.
Constructed from full 409 stainless steel, this system features large 3.00-inch mandrel-bent main tubing that flows into a specially tuned resonator, maximizing exhaust flow while producing an aggressive exhaust note. The exhaust then transitions through a Scavenger Y-collector, splitting into dual 2.50-inch tailpipes for balanced exhaust flow and performance.
The system is finished with dual 4.00-inch carbon fiber exhaust tips featuring an angled cut and rolled edge design. These tips exit cleanly through the factory exhaust cutouts in the rear valance, maintaining a factory-correct appearance with a high-end performance finish. Designed for ease of installation, this cat-back exhaust uses factory hanger locations, includes all necessary hardware, and comes with detailed installation instructions for at-home installation.
