Using this BLOX Racing Axle Back Exhaust is easy. First, make sure your vehicle is a 2015 - 2021 Subaru WRX or 2015 - 2021 Subaru STi (non SPT). The kit is a direct bolt - on, so you just need to remove the old OEM muffler and attach the new one using the included hardware and gaskets. It bolts to a 2 - hole exhaust flange, so double - check that before installation. Important to note, this exhaust won't work with aftermarket exhaust systems and doesn't fit SPT exhaust. For maintenance, since it's made of T304 stainless steel, it's quite durable. But you can clean it regularly with a mild stainless - steel cleaner to keep it looking shiny and prevent rust. Check the bolts and gaskets periodically to make sure they're tight and in good condition. If you notice any unusual noises or performance issues, have it checked by a professional.
