About the Borla Cat-Back S-Type Exhaust
The Borla Cat-Back Exhaust S-Type exhaust system for the Ford Focus ST delivers a powerful sound that you will be proud of. This particular exhaust system is designed to sit behind the factory catalytic converter, hence the name Cat-Back. This is an important design element that ensures the car stays emissions compliant, even with a louder, more aggressive sound.

This replacement performance exhaust system is easy to install. It simply bolts into place, with no need to grab a welding torch, using the car’s existing factory hanger locations. The muffler is engine specific to the Ford Focus ST 2013-2018 models, so you know it will deliver safe performance from the first time you install it.

If you choose a Borla Cat-Back exhaust system for your Ford Focus ST exhaust, it will replace the entire factory exhaust system. On most vehicles, this means it installs directly behind the factory service point. To install, simply disconnect the existing exhaust system and install the Borla model using the existing factory hangars and rubber isolation. This means no cutting of the exhaust system!

Once installed, this exhaust system gives you the ability to have that deep growling sound you want in a low RPM, but also transitions to a quieter sound at normal cruising speed. Your Ford Focus ST will continue to be a car you can use every day. It will sound aggressive when you’re taking off, then settle into a barely audible range when you are at cruising speed. Borla exhaust systems are always "drone-free"!

Borla exhaust systems are constructed from 300-series stainless steel, so they will resist corrosion and stand up well under normal wear and tear. The dual tips are made with 304 stainless steel, so they look as attractive as they sound. This will give your Ford Focus ST a customized look to stand out on the street!
