TurboXS designed an exhaust that remedied some of the shortcomings of other systems for the 2015-2021 WRX and STI. 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/J-pipe, 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, you'll want to use an adapter.
Fits all 2015-2021 WRX and STI .
