Fitment Information: This exhaust fits 2015 - 2021 Subaru WRX and 2015 - 2021 Subaru STI, but won't fit the 2019 STI or the 2018 STI R/A. It only works with an OEM or OE fitment mid pipe, not the SPT exhaust or other aftermarket systems. Features: The Nameless Performance Axleback Exhaust is a great choice for a quick sound and look upgrade. It replaces two 13.5lb factory restrictive 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, offering the loudest axle back option. The factory - fit laser - cut flanges and 2 - inch dual piping have the same flow as a 3 - inch single straight pipe, boosting high - end horsepower and increasing low - end torque by about 10hp/11ft lb at the wheels. You can easily upgrade to a full catback exhaust later by buying the Nameless 3 - inch Midpipe. Nameless Performance parts fit directly with factory exhaust components and are easy to install.

Using this exhaust is quite simple. First, make sure your vehicle is the right model (2015 - 2021 Subaru WRX or most 2015 - 2021 Subaru STI models). Check that you have an OEM or OE fitment mid pipe because it won't work with SPT or other aftermarket exhausts. When installing, use the included full hardware kit and follow the installation guide. It's designed to fit directly with factory exhaust components, so the process should be straightforward. While using the exhaust, keep in mind the California Prop 65 warning. Avoid breathing the exhaust, and don't let the engine idle for long periods. When it comes to maintenance, since it's made of T304 stainless steel, it's relatively durable. But it's a good idea to check the connections and the pipes regularly for any signs of damage or looseness. If you want to upgrade later, you can buy the Nameless 3 - inch Midpipe to turn it into a full catback exhaust.
