2014-2018 Fiesta ST Catback Exhaust by MAPerformance

When it comes to Fiesta ST catback exhausts, few things matter as much as sound. Other companies ignore these things, and it's obvious. But at MAPerformance, we take care to focus on the little details in order to bring out the best in each and every catback we built.

For example, few other companies use in-house mandrel bent stainless steel tubing. We do. We even go a step further to measure the accuracy of each bend. From there, we carefully mock up our exhausts on our custom-built in-house jigs to ensure the most accurate fitment possible. Lastly, our expert fabricators TIG weld each flange and joint with their superior back-purging techniques to ensure each weld lasts as long as the life of the car, while never leaking. Finally, each weld is inspected for imperfections before being sent off to our shipping department for shipment.

That's just part of what makes the MAPerformance Fiesta ST Catback special. Of course, the sound it creates is nothing to shy away from either. You'll get an aggressive, throaty roar with the addition of a few extra ponies as well.

Perfectly "tuned" sound

This is the way Ford should have had the car sound from the factory. Great low tone that gives the car a very "tuned" sound. Not at all raspy or obnoxious and nothing that will offend your spouse or neighbors, but definitely enough to add fun factor to your next cruise. Install was a breeze. I tried first with the factory exhaust hangers, but the system just had too much movement in it so I installed the COBB's and would highly recommend they be used. When connecting to a factory downpipe you'll be using the stock nuts and I'd also recommend adding some washers to them as the holes in the CBE are rather large. I'm finding my tips are a bit too high but lowering them causes the mid-pipe to rest on the factory "I" brace which I plan to add some washers beneath to get me the extra clearance I need to lower the tips a bit getting the away from the bumper. Thanks again to everyone a MAP for making this a great experience for me. I'm local and have the honor of grabbing these parts in person, always a pleasure!

Great exhaust No Drone Nice sound

I worked on a friends car mild upgrades and give car some new life and sound. Installed with a cobb stage 1 plus. After a few runs it breaks in and has a good tone not annoying. I was doing launch control and it sounds like a street rally car without attracting the police. Great fitment and quality.

5-year update

I have gotten so many compliments over the years about the sound of this exhaust. It's a thing of beauty, deep, muscular and ever present but never too loud. Great steel too, the system has no deterioration after five years in Virginia. This gets my highest recommendation.

Honestly the only way it could be better is if got bumped up to 3" which I'd buy... lol

Had this exhaust for about a year now. It's a lovely piece of work and still looks shiny after the heat cycle. Great sound under acceleration, no drone, she even pops on the heel and toe most times. Honestly the only way it could be better is if got bumped up to 3" which I'd buy... lol

Install went great, and Included all of the necessary hardware. Mated with a cobb DP the exhaust is does not drone but is more or less just dense sounding under load. Sounds great and is not stupid loud, can barely even notice cruising in town or on the highway, yet having a relatively throaty deep tone under acceleration. Exhaust hangs a little high and to the passenger side but I'm sure with some minor adjustments it will sit just right. Overall very happy with the product!
