MRT Extreme Cat Back Exhaust (92W000) - 2014-2019 Ford Fiesta ST
Turn your Fiesta ST into a true head-turner with the MRT Extreme Cat Back Exhaust. Designed for drivers who want maximum sound and aggressive performance, this system delivers a bold, unmistakable exhaust tone that commands attention in every driving condition.
Built from premium T304 stainless steel, this cat-back system features 2.5 inch mandrel-bent tubing to improve exhaust flow and reduce restriction. The straight-through, free-flowing design eliminates the factory muffler, unlocking a more aggressive sound profile while enhancing throttle response and overall performance. Dual 3 inch double-wall polished stainless steel tips with beveled edges complete the look, with an optional Black Ops matte ceramic finish available for a stealthier appearance.
The MRT Extreme system is the loudest option available for the Fiesta ST lineup, producing an aggressive growl at idle and a raw, race-inspired tone under acceleration. While it delivers maximum sound, it maintains a controlled level of drone for a more comfortable driving experience.
