mountune High Flow Exhaust, Fiesta ST 2014-2018

mountune has been engineering exhaust systems for years with the objective towards increased power and response coupled with an enhanced exhaust tone and appearance. Our Fiesta ST (B299 ST) High Flow Cat Back Exhaust system is manufactured from 2.5” AISI 304 Stainless Steel (EN58E) mandrel bent tubing with dual 3.25 double walled, polished stainless steel tips.

Additionally, a Helmholtz chamber design is utilized in the rear silencer to cancel out unwanted frequencies. Utilizing this system, despite being more complicated and expensive to manufacturer, ensures back-pressure remains low, providing the optimum in terms of performance while removing as many of the unwanted frequencies and drone as possible.

All muffler assemblies are robotically TIG welded AISI 304 Stainless Steel for long life under extreme performance. Tubing diameter also has a major impact on sound quality and careful consideration was given to size and performance. We have also incorporated slip fit connections at various strategic points to allow for easy installation and adjustment. Limited Lifetime Warranty.

  • High-flow cat-back exhaust design improves performance
  • Engineered Helmholtz resonator for a less intrusive sound
  • High quality stainless construction with CNC welds
  • Staggered, twin-tailpipe trims with laser-etched mountune logo
  • Limited lifetime warranty
  • Robust OE Type mounting bracket and hangers
  • Manufactured from AISI 304 2.5” mandrel bent Stainless Steel tubing
  • Dual 3.25" AISI 304 polished stainless steel tips with stylish tapered design
  • Robust AISI 304 Stainless Steel hanger assemblies

mountune cat-back exhaust - 3 month review August 16, 2018
Reviewer: Marc from Prince George, BC  
Had my mountune cat-back exhaust installed in May 2018 and it been about 3 months since having it installed and have to say WOW mountune has done an awesome job designing this exhaust system. The quality of the actual exhaust is A+ and what you see on the website for pictures is what you get. The sound of this exhaust in my opinion is one of the better if not the best sounding exhaust for the Fiesta ST. It's loud when you want it to be loud and quite when your cruising at a lower rpm. You get a nice snap, crackle, pop and occasional backfire on hard decel which is nice too and with windows up isn't as noticeable. It has a deeper bass level compared to stock and is louder from about 3-4000rpm but pushing to redline doesn't sound much if at all louder compared to stock. This is my first after mark exhaust system and have to say I'm 100% satisfied with this purchase.

Excellent product with one caveat October 30, 2017
Reviewer: John Sandoval from Philadelphia, NY United States  
Exhaust system was delivered in perfect condition. Had it installed at my local Ford dealer (a mechanic I trust, only 1.5 hours of labor) and immediately found that the stock exhaust hangars are not strong enough to hold this system in place securely. Lots of movement and crashing/banging on the way home. Called Mountune and had them overnight their upgraded exhaust hangars which are a perfect solution. I wish Mountune would charge $50 more for the exhaust and include these hangars with the kit or at least mention in the product description that this exhaust is unusable with stock exhaust hangars. I don't have any other mods done to my engine, that being said the car feels a bit more eager above 3000 rpm and sounds fantastic. Nice tone without drone at steady throttle. You can have a normal level conversation at 75 mph with no problem. I would recommend this kit to any FiST owner, just make sure you get the upgraded hangars too.

Great Sound September 7, 2017
Reviewer: Christopher Cabral from Bradford , RI United States  
Easy install and a high quality construction.  It was back ordered for a bit longer than I expected, but worth the wait.  No obnoxious droning, just a great throaty sound and a great look.

Great Product and Customer Service February 17, 2017
Reviewer: Kevin Tailford from Redford, MI United States  
Exhaust was back ordered, but I was in no hurry.  Once the unit was shipped, it arrived quickly, and very well packaged.  So far, the quality looks top notch.  I will be installing this weekend.   I will follow up with more comments once installed.

Mountune 5-Door CBE February 10, 2017
Reviewer: Max from CA  
Quality product with excellent sound.  Drones a bit more than I was expecting at certain RPMs, but I think a sound symposer delete may be necessary to help quiet things down.

I do recommend getting stiffer hangars as the stock hangars move FAR too much and allow the exhaust to bang around under hard driving conditions.
