Built specifically for the 2013-2018 Ford Focus ST 2.0L EcoBoost, the MBRP S4201AL cat-back exhaust routes spent gases through a 3-inch aluminum system and exits through a dual outlet configuration that transforms the ST's exhaust note and reduces backpressure in the process.
Three-inch diameter piping from cat to tip. The larger-diameter tubing reduces restriction through the exhaust path, letting the turbocharged 2.0L EcoBoost breathe more freely and maintain exhaust velocity where the factory system compromises it.
Dual outlet exit. The split rear exit gives the Focus ST an aggressive, symmetrical stance at the bumper while improving flow over a single-exit configuration. The visual upgrade matches the ST's sport-oriented bodywork without requiring any bumper cutting or bracket fabrication.
Aluminum construction keeps weight in check. The aluminized steel construction balances durability with a weight advantage over heavier aftermarket options, making it a practical choice for a car that rewards light builds and responsive dynamics.
Designed for a direct bolt-on fit. MBRP engineers the S4201AL to use factory mounting locations on the 2013-2018 Focus ST, so installation requires no welding, cutting, or custom fabrication. All necessary hardware is included.
