Injen Performance Cat-Back Exhaust System is engineered for the 2015-2021 Subaru WRX and WRX STI. Its custom dual muffler design produces a distinctive auditory experience, combining a deep idle rumble with an aggressive, high-rpm roar.

The polished mufflers and burnt titanium-look tips enhance the system’s visual impact. Designed for swift installation, the system utilizes V-band clamps, flanges, and factory mounting points, eliminating the need for modifications.
