In 2003, Injen Technology launched our Super SES stainless steel cat-back exhaust systems complementing our line of air intake systems. Each exhaust system was equipped with the Injen signature style slanted mufflers and features highly polished stainless steel.

Injen's Ford Focus ST catback exhaust system is just another solid production coming from Injen. Featuring polished stainless steel for strength, durability, and a clean look, it also adds burnt tips to add a perfect amount of style to an already high performing hatch. This is help clear the exhaust gases being thrown to the back of the car through the turbocharger and increase efficiency and power simultaneously.
