Roush 3" Cat-Back Exhaust Kit for all 2013, 2014, 2015, 2016, 2017 and 2018 Focus STs.

This Roush Exhaust kit has a performance-flow muffler and uses 3" diameter tubing that helps the turbocharged Focus expel gasses faster for increased power. Mandrel bent 409 stainless steel tubing also helps to achieve optimum air flow in this system. The whole exhaust system utilizes factory mounting locations for a straight forward install that you can do yourself, at home, with only basic hand tools.

Kit Includes:
- Performance-Flow Muffler
- Mid-Pipe Assembly
- Y-Pipe Assembly
- Dual 4" Exhaust Tips
- All Necessary Hardware
- Installation Manual

Please Note: Ford designed the 2015 Focus ST with four exhaust hangers but only added three on the factory exhaust system. All aftermarket exhaust systems are built to use that fourth exhaust hanger. CJ Pony Parts recommends the purchase of COBB’s Polyurethane Exhaust Hanger Kit (591001).

This Roush 3" Cat-Back Exhaust Kit for all 2013-2018 Focus STs features dual, 4" round 304 chrome flashed tips with rolled edges and stamped Roush logos, center exiting the car. Roush's cat-back enhances the exhaust note and pitch of your Focus ST for a high-performance sound that will surely garner some attention. Between the large diameter piping used, the straight-forward uninhibited air path and performance-flow mufflers, this exhaust kit will achieve some significant horsepower and audible performance gains.
