Injen Stainless Steel Exhaust System for 2021 Subaru WRX STI

Injen has always been great at getting maximum airflow into your motor. Now they have turned their attention to making exhaust systems to match that increased airflow for power gains across the RPM range of your Subaru WRX STI! Starting with 304 stainless steel each system is computer assembled from bending, to CNC'd flanges, through final assembly welding. This guarantees a great fit and consistent performance from every system. The Super SES exhaust systems utilize a flow-through muffler for maximum power and an aggressive tone. Finally each exhaust is finished off with Injen's embossed flared tip design for show stopping looks to compliment the additional power.
