Using this Remark axle - back exhaust is a breeze. First, make sure your vehicle is a 2015 - 2021 Subaru WRX or STI and has a Standard OEM Midpipe or a REMARK Midpipe kit. It won't work with aftermarket exhaust systems. For installation, it's a direct bolt - on to the OEM or Remark mid Y - pipe. Just follow the instructions and use the included gaskets and bolts. When it comes to maintenance, since it's made of high - quality 304 stainless steel, it's quite durable. But it's a good idea to clean it regularly with a mild stainless - steel cleaner to keep it looking shiny. Avoid using harsh chemicals as they may damage the finish. Also, check the bolts periodically to make sure they're tight. If you notice any unusual noises or vibrations, it might be a sign that something needs to be checked. And remember, if your vehicle has an SPT midpipe, this isn't the right exhaust for you. You should look at our Remark SPT axle - back exhausts instead.
