Upgrade your 2015 - 2021 Subaru WRX or STI (excluding 2019 STI and 2018 STI R/A) with the Nameless Performance Axleback Exhaust. This exhaust is a great choice for a quick sound and look improvement. It replaces the two heavy 13.5lb factory restrictive baffled mufflers with mandrel - bent, TIG - welded, T304 stainless steel pipes. You can also configure the tailpipe tip style to your liking. The 4 - inch muffled axleback exhaust comes with 3.5 - inch Neochrome single - walled tips. It features factory - fit laser - cut flanges and 2 - inch dual piping, which has the same flow as a 3 - inch single straight pipe. This provides excellent breathing for high - end horsepower and boosts low - end torque by about 10hp/11ft lb at the wheels. If you want more torque, you can easily upgrade to a full catback exhaust by buying the Nameless 3 - inch Midpipe. The parts fit directly with factory exhaust components and are easy to install. Key features include 4 - inch mufflers, 3.5 - inch exhaust tips, single - wall tip style, Neochrome tip color, staggered and quad exits, laser - cut flanges, T304 stainless steel construction, mandrel - bent piping, TIG welding, direct fit to OEM mid - pipe, factory - style exhaust hanger rod, a full hardware kit for installation, and an installation guide. Note: This product only works with an OEM or OE fitment mid - pipe and won't work with SPT or other aftermarket exhaust systems. California Prop 65 Warning: Operating, servicing, and maintaining a vehicle can expose you to harmful chemicals.

Using your Nameless Performance Axleback Exhaust is easy. First, make sure your vehicle is an appropriate 2015 - 2021 Subaru WRX or STI (excluding 2019 STI and 2018 STI R/A), and that you have an OEM or OE fitment mid - pipe. The exhaust comes with a full hardware kit and an installation guide. Follow the guide step - by - step to install it correctly. During installation, pay attention to the factory - fit laser - cut flanges and ensure they are properly aligned. Once installed, you'll notice an immediate improvement in sound and performance. When it comes to maintenance, keep an eye on the T304 stainless steel pipes. You can clean them regularly with a mild stainless - steel cleaner to keep them looking shiny. Also, check the TIG - welded joints periodically for any signs of wear or damage. Regarding the exhaust tips, wipe them down occasionally to maintain their Neochrome finish. Remember, operating your vehicle can expose you to harmful chemicals. So, avoid breathing the exhaust, don't idle the engine more than needed, service your vehicle in a well - ventilated area, and wash your hands or wear gloves when working on it.
