Description
Overview
The Flowmaster Outlaw Cat-back Exhaust System is engineered for drivers who want their Ford Focus ST to be heard as well as seen. Designed specifically for all 2013-2018 Ford Focus ST models equipped with the 2.0L turbocharged engine, this Outlaw-series system delivers an unapologetically aggressive sound level inside and out. If you’re the type of enthusiast who welcomes the attention, this is the exhaust built to match your personality.
At the heart of the system is large 3.00-inch mandrel-bent stainless steel tubing that flows into a specially tuned reflection-style resonator for maximum performance and sound. From there, a Scavenger Y-collector splits the flow into dual 2.50-inch tailpipes, finished off with a pair of large 4.00-inch carbon fiber tips that exit cleanly through the factory exhaust cutouts in the rear valance for an aggressive, purposeful look.
Key Benefits
Every detail of the Outlaw cat-back is designed to combine bold styling with a straightforward, at-home installation. The system mounts using all the factory hanger locations, so there’s no fabrication or guesswork required. It also includes all necessary hardware and detailed instructions, making it a satisfying weekend upgrade for the DIY builder.

The single-outlet muffler design routes into the dual-tip layout for that signature Outlaw presence.
