Description
The Mishimoto Fiesta ST Cat-Back Exhaust (MMEXH-FIST-14BK) is the Non-Resonated, Black Tips version of Mishimoto’s performance exhaust system built specifically for the 2014-2019 Ford Fiesta ST. Machined entirely from mandrel-bent, TIG-welded 304 stainless steel, this system carries a 2.5-inch overall diameter designed to help the 1.6L EcoBoost engine breathe while producing a subdued yet aggressive exhaust and turbo tone under acceleration and boost.
Built to mate directly with the factory downpipe, this Mishimoto cat-back exhaust replaces the mid-pipe and rear muffler section with fully stainless steel components, so you don’t have to worry about corrosion compromising the system’s flow or introducing exhaust leaks over time. The dual 3-inch offset tips on this option arrive in a black, round, double-wall design with a matte finish, slip-fit connection, and an angle cut, giving the rear of your Fiesta ST a distinct look to match its sound. Backed by the Mishimoto Lifetime Warranty and designed for an installation that can be completed in under one hour, this Fiesta ST exhaust is built for owners who want a performance cat-back without a complicated install.
Vehicle Applications
