Upgrade your Ford Fiesta ST with the Injen Technology Part Number injSES9016RS, a high-performance cat-back exhaust system designed for 2014-2019 models equipped with a 1.6L turbocharged 4-cylinder engine. Crafted from premium 304 stainless steel, this exhaust features mandrel-bent tubing that ensures smooth airflow and optimal performance. Handcrafted and TIG welded in the USA, the system includes all necessary hardware, flanges, and mufflers for a straightforward installation without the need for cutting or welding. The polished, burnt titanium tip adds a striking visual touch, enhancing your vehicle's sporty appearance.
The system is engineered to deliver an aggressive sound while increasing horsepower and torque, with dyno-proven gains of up to 6 horsepower and 7 lb-ft of torque. Dual Injen resonators work to produce a clean, crisp, sound that emphasizes performance without excessive drone. The full 76mm piping diameter maximizes exhaust flow, contributing to improved engine efficiency and power output. Designed for a hassle-free upgrade, this exhaust system provides a show-quality finish and durable stainless steel construction for long-lasting performance.
Whether you're seeking improved sound, enhanced power, or a more aggressive look, the Injen cat-back exhaust system is an excellent choice. It complements the Fiesta ST's turbocharged engine, offering a noticeable boost in performance and a distinctively sporty exhaust note. Made in Pomona, California, this system combines quality craftsmanship with easy installation, making it a popular upgrade for enthusiasts aiming for a bold, refined appearance and optimized engine performance.
