2013-2018 Focus ST EcoBoost MBRP Pro Series 3" Cat-Back Exhaust Kit S4200304

Aggressive and High Quality MBRP Focus ST Cat-Back System

Despite their impressive power and nimble quickness, our dear friends at Ford didn't see fit to give the hot hatch 2013 to 2018 Focus STs the deep, mean rumble that their fiery 2.0L EcoBoost motors really deserved. Our friends over at MBRP are here to pick up the slack with one of the highest quality Focus ST cat-back exhaust systems on the market. The MBRP Pro Series cat-back exhaust system is made from top-quality steel and features both larger and more efficient exhaust tubing and mufflers that helps improve overall performance while giving your quick ST an awesome, new sound. MBRP's complete Focus ST cat-back exhaust system bolts on right in place of stock and doesn't require any PCM tuning, making it easy to change the sound and feel of your awesome hot hatch.

Features 3" Diameter 304 Stainless Steel Tubing

MBRP builds each of these Focus ST cat-back exhaust systems from the ground up to improve efficiency over stock. The system is manufactured out of 3" diameter tubing that is all carefully mandrel-bent to provide smooth exhaust outflow with far less back pressure and restrictions over stock. The Pro Series system is made out of high-quality 304 stainless steel that can resist rust, corrosion, and discoloration in practically any climate. The system come with both a new muffler and resonator that work together to give your ST a deep, mean sound without a ton of cabin drone at idle or highway speeds. The kit comes standard with a pair of polished 304 stainless steel exhaust tips for a whole new look. Each MBRP cat-back exhaust kit come standard with instructions and the necessary hardware and clamps for installation.
