Using your Remark axle back exhaust is straightforward. First, make sure your vehicle is a 2015 - 2021 Subaru STI or WRX and that you have either the Standard OEM Midpipe or a REMARK Midpipe kit. This exhaust won't work with aftermarket exhaust systems. Installation is easy as it's a direct bolt - on to the OEM or Remark mid Y - pipe. Just 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 check the bolts and gaskets periodically for tightness. If you notice any rattling or unusual noises, that could be a sign that a bolt has come loose. Keep the exhaust clean by washing it with a mild soap and water solution. Avoid using abrasive cleaners as they can damage the finish of the single wall polished tips. If you want the best performance, consider pairing this axle back exhaust with a Remark mid pipe to get a complete cat back exhaust system.
