The MKIII Focus ST shook things up when it came to the US market, and the aftermarket was quick to develop parts to pull 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.
Aggressive sound. With smooth, mandrel-bent, 3 inch T304 stainless steel tubing, this cat-back gets rid of restriction. This improved flow and the high-flow resonator result in a race-ready sound that suits the Focus ST.
Increased performance. Tested in-house to verify results, this cat-back results in gains of up to 13hp and 15 lb-ft of torque. If you are after an easy upgrade that makes driving more exciting, gives your Focus a new sound, and adds power, this exhaust kit is the perfect upgrade.
