TurboXS offers this adapter to mate an OEM downpipe to a 3" catback on Subaru models; the kit includes both a stainless exhaust gasket and an OEM-style donut gasket to ensure proper sealing between differing flange types. It provides a practical sealing solution when combining a 3" system with the stock downpipe connection on compatible Subaru turbo applications.
