13-18 Focus ST Ecoboost MRT Street Race Axle Back

The Street Race Axle Back is a loud, aggressive MRT exhaust system for your Focus ST. This sporty variation on the third-generation Focus looks like an aggressive compact sports car, but the stock 2.0L EcoBoost engine and exhaust produce a somewhat puny sound. By installing this 2013-18 Focus ST Axle Back Exhaust, you'll have the tone to match its sleek exterior. The exhaust has just enough exhaust presence with elevated sound to Get Noticed, plenty of opportunity to Feel the Performance and packaged in a design without excessive drone.

American-Quality Exhaust Performance

The Focus ST MRT Street Race Axle Back has a loud, deep muscle car sound and is handcrafted from T304 stainless steel. This system includes 2.5-inch mandrel-bent tubing and dual four-inch double wall, polished T304 stainless steel tips with beveled edges. If you want a bolder accent, upgrade to our "Black Ops" dual-tip blackout using heat-resistant ceramic.

This system is engineered for the best sound to match your vehicle and provides increased performance from the increased exhaust flow. It's designed for DIY backyard installation using the included hardware plus common hand tools like ratchets, sockets and pliers.
