Product Description

The TurboXS WS02-SBE Stealthback is a downpipe-forward exhaust system for the 2002-2007 Subaru WRX, 2004-2007 WRX STI, and 2004-2008 Forester XT. Designed for owners who want performance gains while retaining a stock look and sound, the Stealthback mates to the factory muffler rather than replacing it. The system includes a cast 304 stainless steel bellmouth downpipe that tapers into a full 3-inch midpipe, connected via an OEM-style ball-and-socket joint with a donut gasket for a sealed, flexible fit. A high-flow 100 cpi metal substrate catalytic converter is integrated into the downpipe assembly.

The Version 2 midpipe features a unique dual bolt pattern rear flange, allowing the system to connect to either the OEM muffler or a TurboXS full 3-inch aftermarket muffler. The downpipe will also bolt to any stock or 3-inch aftermarket catback. An O2 extender or ECU tune may be required to prevent a check engine light. Not CARB legal -- not for street use in California. OEM muffler not included.
