The Turbo XS turboback exhaust system for 2002–2007 Subaru WRX/STi replaces the entire downpipe-to-exit path and includes a high-flow catalytic converter and 4" black outlet. As a full turboback layout, it improves exhaust flow through mandrel routing and a catted section while fitting the WRX/STi models listed. The system is presented as a complete direct-replacement exhaust option for those vehicles.
