Nameless Performance Midpipe 2022-2023 WRXReady to turn your Axleback exhaust into a catback exhaust? Our Nameless Performance 2022 Subaru WRX Midpipe features a 3" primary circuit with a unique Y section that ensures optimal flow transition from the main 3" circuit into our 2" rear circuit axleback exhaust. The Y features a stepped design which puts larger diameter tubing at the transition of gas flow as the exhaust is split from the main circuit into each of the rear circuits of the system
