The most popular option is the cat-back exhaust kit for the Focus ST. The cat-back exhaust kit replaces the entire exhaust system in your Ford Focus ST, from the catalytic converters rearward, including the intermediate pipe, mufflers and the exhaust tips. For Ford Focus ST owners still with the factory system, a new cat-back exhaust kit will remove much of the restriction, which will result in increases in horsepower and torque throughout the curve.

A cat-back exhaust kit for your Focus ST will also help with the sound. With new mufflers and removal of the factory resonators, you can get the sound you would have expected from the 2.0L EcoBoost engine in the Focus ST. Oftentimes, with high-quality exhaust tips, the new cat-back exhaust kit in your Focus ST can give a nice look, too.

With so many benefits, there isn't any reason why a Ford Focus ST owner wouldn't upgrade to a new cat-back exhaust kit. However, with CJ Pony Parts' huge selection of cat-back exhaust kits, it's silly not to upgrade. There are more than a dozen options, with more being added regularly, so CJ Pony Parts can help you find the perfect sound and style for your Focus ST. Most cat-back exhaust kits on CJ Pony Parts also feature video install guides and sound clips, which can aid in your decision.
