TurboXS designed an exhaust that remedied some of the shortcomings of other systems for the 2008-2014 STI and 2011-2014 WRX. Some other exhausts have pipes that hang too low, giving a "sewer pipe" appearance under the car. The TurboXS system tucks up nice and tight to the car for a tidy look from the back. Some exhaust systems are surprisingly quiet, but the TurboXS system has a deep, authoritative boxer tone that Subaru enthusiasts know and love.
Of course, like all TurboXS exhaust systems, it's fabricated from all mandrel-bent, fully polished 3" stainless steel tubing. A nice set of rolled and flame-blued 4" tips completes the look.
Note that this cat-back fits best with a flat-flange downpipe, either the TurboXS, Invidia, or other aftermarket. It can be fitted to the factory downpipe, but because of the donut gasket on the factory downpipe, the fit will not be perfect.
Fits all 2011-2014 WRX and STI SEDAN (not hatch).
