Injen 14-19 Ford Fiesta ST 1.6L Turbo 4Cyl 3in Cat-Back Stainless Steel Exhaust w/ Burnt SS Tip

If you're looking to give your 2014-2019 Ford Fiesta ST a more aggressive sound and a noticeable boost in performance, this Injen cat-back exhaust system is a solid choice. It's designed to replace the factory exhaust from the catalytic converter back, improving exhaust flow and giving your 1.6L turbo engine a distinct voice.

This system is built from 3-inch diameter, 304-grade stainless steel tubing that's CNC mandrel-bent. Mandrel bending is key because it keeps the tubing's diameter consistent throughout the bends, ensuring smooth airflow without any restrictions. Injen includes dual resonators in this setup, which help produce a clean, crisp exhaust note that's unmistakably Injen, without being overly raspy. The system also features investment cast stainless steel flanges and custom hangers, all TIG welded by hand right here in the USA. You'll also get a handsome 4.5-inch burnt stainless steel tip with a rolled edge to finish off the look.

Installation is designed to be straightforward, with all the necessary hardware and hangers included. Injen claims dyno-proven gains of up to 6 horsepower and 7 lb-ft of torque with this system, which is often complemented by their performance intake systems. This is a well-built system that not only sounds great but also looks the part and is made to last.
