Here's what our ST Specialist Nick had to say:
Since this car is my personal daily-driver, it was important to me that I find an exhaust that I could love and live with daily, that my significant other wouldn’t hate either. The COBB Turbo-Back Exhaust system for Fiesta ST will really wake up your Fiesta ST’s performance and also delivers a great exhaust note that cracks and pops (in a good way) when you engine brake.









  • Cast/Machined turbo flange
  • Full 304SS Construction
  • 4"" Flex Section
  • 200 Cell Count Metal Spun Catalytic Converter
  • 3” 304SS Up to Catalytic Converter, 2.5” 304SS From Flex to Flange




The COBB Stainless Steel Catted Downpipe for the 2014 Ford Fiesta ST is a direct replacement unit which features full 304 stainless steel construction, billet machined turbo flange and a high quality metal spun catalytic converter. All of these features combine into an excellent replacement for the power robbing factory unit!
