The TurboXS 3" downpipe-to-OEM catback adapter for Subaru WRX/STi provides a simple mating solution between a 3-inch downpipe and the factory donut-style catback flange. This adapter is supplied with an OEM-style donut gasket to ensure a proper seal at the connection and to avoid exhaust leaks when combining a larger downpipe with the stock catback configuration.
