Injen Technology

Injen Technology has made it a point to stay at the forefront of performance technology making only the best air intake one can envision. In 1999 Injen was faced with such a strong demand in both US and Canada that in order to meet production schedules it became essential to branch out and add a second building.

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