MagnaFlow 2-1/2" Stainless Steel Cat-Back Exhaust System with 4-1/2" Polished Tips for 2013, 2014, 2015, 2016 and 2017 Focus ST.
MagnaFlow's cat-back system consists of 2-1/2" mandrel bent stainless steel tubing. All parts are welded together and built to last. A 5"x14" resonator sits in front of a 5"x14" muffler which creates a smooth and deep exhaust tone. Dual 4-1/2" polished tips exit the center of the rear bumper. Not only does the Magnaflow cat-back provide your Focus ST with a great exhaust sound, but it increases the horsepower of the 2.0L turbocharged engine.
- 2-1/2" Stainless Steel Tubing
- Dual 4-1/2" Exhaust Tips

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. We recommend the purchase of COBB’s Polyurethane Exhaust Hanger Kit (591001).
Let this be one of the first modifications you make on your Focus ST. Upgrading the exhaust increases horsepower and provides a louder exhaust note that will be like music to your ears. MagnaFlow's cat-back bolts in place of your original exhaust. Just like all MagnaFlow products, this exhaust system features high-quality components for long lasting life. Made in the USA!
