Increase the power of your 1.6l turbo Ford Fiesta ST with the help of a nice catback exhaust system from Injen. Featuring stainless steel construction for excellent durability, 3" piping for awesome flow, thick flanges for solid mounting, and ultimately, a well put together exhaust for quality sound and fitment. The Injen exhaust also features a burnt tip so you know your ST is separate from the ordinary. This is a perfect supporting modification for getting much more power out of your ST than what the factory gave it or if you just want a nice sporty tone.
