Upgrade your Subaru WRX (2015 - 2021) or STI (2015 - 2021, except 2019 STI and 2018 STI R/A) with the Nameless Performance Axleback Exhaust. This exhaust is a game - changer for a quick sound and appearance boost. It replaces the heavy, restrictive factory mufflers with mandrel - bent, TIG - welded T304 stainless steel pipes. The 5 - inch muffled axleback comes with 4 - inch polished single - walled tips, giving your car a sleek look. The laser - cut flanges and 2 - inch dual piping offer great flow, similar to a 3 - inch single straight pipe. This setup increases high - end horsepower and adds about 10hp/11ft lb of low - end torque at the wheels. If you want more torque later, you can easily upgrade to a full catback exhaust by buying the Nameless 3 - inch midpipe. It fits directly with factory exhaust components, and installation is a breeze. Features include 5 - inch mufflers, 4 - inch tips, single - wall tip style, polished tip color, staggered and quad exits, laser - cut flanges, and a full hardware kit. Please note, it only fits with an OEM or OE fitment mid - pipe and won't work with SPT or other aftermarket exhausts. Also, be aware of the California Prop 65 warning about exposure to harmful chemicals when operating and servicing your vehicle.

Using the Nameless Performance Axleback Exhaust is straightforward. First, make sure your vehicle is a 2015 - 2021 Subaru WRX or a 2015 - 2021 STI (not the 2019 STI or 2018 STI R/A) and has an OEM or OE fitment mid - pipe. The exhaust comes with a full hardware kit, so you can use those parts for installation. Just follow the included installation guide. When installing, work in a well - ventilated area to avoid breathing in exhaust fumes. For maintenance, regularly check the T304 stainless steel pipes for any signs of rust or damage. You can clean the polished tips with a mild metal cleaner to keep them looking shiny. If you notice any unusual noises or a decrease in performance, it might be a good idea to have the exhaust checked by a professional. And always remember the California Prop 65 warning. Don't idle the engine more than necessary, and wash your hands often if you're working on your vehicle.
