Cobb Ford Focus ST SS 3in Catback Exhaust

This is Cobb's 3-inch stainless steel catback exhaust system specifically for the 2013-2015 Ford Focus ST. If you're looking to give your Focus ST a more aggressive exhaust note and improve exhaust flow, this system is a solid choice. It replaces the factory muffler and exhaust piping from the catalytic converter back, offering a more direct path for exhaust gases to exit the vehicle.

Constructed from 3-inch diameter, mandrel-bent T304 stainless steel tubing, this catback is built to last. The stainless steel construction resists corrosion, which is important for an exhaust system that's exposed to the elements. The system includes a straight-through muffler design that helps reduce backpressure while producing a deeper, sportier exhaust tone without being overly raspy or droney at cruising speeds. Cobb has designed this system to fit right, minimizing installation headaches. You'll notice a more responsive feel from the engine as exhaust gases can escape more freely.

This catback exhaust system is designed to bolt directly to the factory catalytic converter, making installation more straightforward. While it's a catback system, meaning it doesn't replace the catalytic converter itself, the improved flow from the larger diameter piping and muffler design can contribute to a more satisfying driving experience. You'll want to ensure you have the necessary tools and potentially a helper for installation, as exhaust work can sometimes be tricky. This system is a popular upgrade for Focus ST owners looking for a noticeable improvement in sound and performance.
