If you are looking to take your Fiesta to the
extreme, look no further. We created the MRT Extreme Exhaust line for the driver who wants the baddest, loudest sound out of their ride. This system has an aggressive growl that will certainly get you noticed and turn heads as you cruise the highway in your Fiesta. The Fiesta ST MRT Extreme Cat-Back is constructed in T304 Stainless Steel for the best corrosion resistance and has polished tips or black out (custom ceramic coated option). This system has 2.5" mandrel bent tube and dual 3" double wall, polished T304 stainless steel tips with beveled edges.
This Extreme Cat Back Exhaust is engineered for the best sound to match the Fiesta ST character and provides increased performance from increased exhaust flow. It is a free flowing system that deletes the stock muffler and improves overall performance. The Extreme Cat-Back has just enough exhaust presence with elevated sound to Get Noticed, plenty of opportunity to Feel the Performance and packaged in a design without excessive drone.
Application: 2014 thru 2019 Ford Fiesta ST
