Upgrade your 2015 - 2021 Subaru WRX or STI (excluding 2019 STI and 2018 STI R/A) with the Nameless Performance Axleback Exhaust. This muffler delete exhaust system is a game - changer. It replaces the heavy, restrictive factory mufflers with mandrel - bent, TIG - welded T304 stainless steel pipes and configurable tailpipe tips.
The 3.5 - inch polished double - walled tips not only look great but also reduce weight and eliminate exhaust restrictions. It's the loudest axle - back option for a powerful sound. The laser - cut flanges and 2 - inch dual piping offer excellent flow, equivalent to a 3 - inch single straight pipe, boosting high - end horsepower and increasing low - end torque by about 10hp/11ft lb at the wheels.
If you want more torque, you can easily upgrade to a full cat - back exhaust by buying the Nameless 3 - inch midpipe. The parts fit directly with factory exhaust components, and installation is straightforward.

Using this Nameless muffler delete exhaust system is easy. First, gather all the tools you'll need from the included hardware kit. The system is designed to fit directly onto your vehicle's OEM mid - pipe, so just follow the installation guide step - by - step. You can customize the look and sound by choosing your preferred tailpipe tip style.
When using your vehicle, remember that this exhaust is the loudest option, so be aware of local noise regulations. To minimize exposure to harmful chemicals, don't idle the engine for too long and always service your vehicle in a well - ventilated area.
For maintenance, regularly check the T304 stainless steel pipes and the laser - cut flanges for any signs of damage or corrosion. If you notice any issues, you can clean the parts with a mild stainless - steel cleaner. Keep the exhaust hanger rods in good condition to ensure a proper fit. If you want to upgrade to a full cat - back exhaust later, simply purchase the Nameless 3 - inch midpipe and follow the installation instructions.
