The TurboXS Bellmouth High-Flow Catted Downpipe (v2) for the 08-14 WRX & STi uses a massive 3.5" cast 304 Stainless Steel Bellmouth that tapers to 3.0" piping where it connects to the mid-pipe. Unlike previous designs, the new TurboXS downpipe will bolt to any stock or 3" aftermarket catback exhaust system. With the new design it's easy to go catless for those race gas kind of days by just replacing the lower section with WS08-RP-V2. This downpipe also includes a second o2 bung for installation of a wideband o2.
Note: This downpipe includes (2) 3" exhaust gaskets & hardware, but a 'turbo-to-downpipe' gasket is not included. (See recommended tab)
