S-Type Cat-Back Exhaust System

The Borla S-Type Cat-Back Exhaust System (140504) is engineered to enhance the performance and sound of your Ford Focus ST. Constructed from premium T-304 stainless steel, this system is built for longevity and resistance to corrosion. Designed specifically for the 2.0L Turbo engine with a manual transmission and FWD drive, this cat-back system replaces the factory exhaust from the catalytic converter back. It features Borla's patented straight-through and multi-core technology, aiming to unleash hidden horsepower and deliver an aggressive, performance-oriented sound. Installation of this Borla system is intended to be a direct bolt-on replacement, though Borla Performance Industries recommends professional installation by an exhaust shop or aftermarket parts installer. Note that this system is not compatible with models featuring the Black Appearance Package, as the dual exit exhaust may not align with the factory bumper. This cat-back exhaust system fits 2013-2018 Ford Focus ST models, including those with the PZEV (Partial Zone Emissions Vehicle) Emissions Package.
