The MKIII Focus ST shook things up when it came to the US market, and the aftermarket was quick to develop parts to wring out more power and even more performance from the hot hatch. This cat-back builds on the impressive looks and performance of the Focus ST and gives it the sound that matches it's performance.

Intimidating sound. With smooth, mandrel-bent, 76mm T304 stainless steel tubing, this cat-back eliminates restriction and spares no expense. The free-flowing design announces your Focus ST with a crisp, clean, and aggressive sound. The dual resonators clean up unwanted frequencies for a more refined sound.

High-end styling. Equipped with tips made from titanium and with tubing made from premium T304 stainless steel, this system sets your Focus apart. The hand-crafted and TIG construction ensures the highest quality, strength, and best fitment.
