The 20192021 STI Catback from Nameless Performance follows a long line of exhaust R&D established by Nameless Performance over the last four years. Following closely in the footsteps of the 1114 WRX/STI Sedan Catback, with a number of improvements and changes to fit perfectly on your 19 STI using the tried and true standard EJ series engine. In testing on the EJ series engine, this catback has shown midrange gains of:

• +32 ft-lb of torque

• +22 hp at the wheels

above and beyond a standard off-the-shelf Stage 1 tune. This performance standard is achieved through a number of innovative design cues that have made Nameless Performance the top name in Subaru aftermarket exhaust development and engineering.
