The Ford Focus ST sounds relatively tame in stock form but a new exhaust system can really help give it a more sporty and aggressive sound. Plus, you can open up the restrictive factory pipes for better airflow and stronger performance. If you’re ready to take your hot hatch to the next level, browse our selection of Focus ST Exhaust kits and accessories. With high-quality options from top brands, there’s something for every enthusiast.
It’s not surprising that aftermarket exhaust upgrades are one of the most popular mods for Focus ST owners. While the stock system is just fine, a performance-oriented exhaust will really unlock the potential in terms of sound and power.
CJ’s offers a great variety of top-notch cat-back exhaust options for your Focus ST, allowing you to pick the style that works best for what you want out of your car. By replacing the factory mid-pipes and muffler, you can get superior airflow, allowing for more horsepower and torque.
With either a cat-back or axle-back exhaust kit, you’re also going to get a great improvement in sound output. Whether you want your exhaust note to be a subtle yet sporty upgrade from stock or a loud, track-ready roar, we’ve got something for every driver. For the most affordable option, you can simply swap out the heavy factory muffler for a performance-oriented one, which will also give you a deeper, more aggressive sound.
