You're getting a complete cat-back exhaust system from Injen, including all the stainless steel tubing, mufflers, and race-style tips. It also comes with the necessary hardware and hangers for installation. This system is built to replace your factory exhaust from the catalytic converter back, giving your 2014-2019 Ford Fiesta ST a more aggressive sound and a noticeable bump in performance.

This Injen system is crafted from 100% 304 stainless steel, which is known for its strength and resistance to corrosion. The tubing is CNC mandrel-bent, meaning it maintains a consistent diameter throughout, allowing for smooth, unrestricted airflow. This design helps bring out a distinct Injen sound, thanks to dual resonators, and the manufacturer claims dyno-proven gains of up to 6 horsepower and 7 lb-ft of torque. The investment cast flanges and custom hangers are TIG welded for durability, and the whole system is designed for a straightforward installation with no cutting or welding required.

This cat-back system is designed to complement performance intake systems, aiming to maximize horsepower and torque across the entire RPM range. The 3.00-inch diameter piping and polished stainless steel tip give it a unique performance look that matches its improved sound and power output.
