Fitment Info: This exhaust fits 2015 - 2021 Subaru WRX and 2015 - 2021 Subaru STI (excluding 2019 STI and 2018 STI R/A). It only works with an OEM or OE fitment mid - pipe, not with SPT exhaust or other aftermarket systems. Features: The Nameless Performance Axleback Exhaust is a perfect choice for a quick sound and look upgrade. It replaces two 13.5lb restrictive factory mufflers with mandrel - bent, TIG - welded, T304 stainless steel pipes and configurable tailpipe tips. With 4 - inch Polished Double - Walled Tips, it reduces weight and removes exhaust restrictions from the OEM muffler, offering the loudest axle - back exhaust option. Factory fit laser - cut flanges and 2 - inch dual piping have the same flow as a 3' single straight pipe, boosting high - end horsepower and adding about 10hp/11ft lb of low - end torque at the wheels. You can easily upgrade to a full catback exhaust later by buying the Nameless 3' Midpipe. Nameless Performance parts fit directly with factory exhaust components and are easy to install.
