Using your new Remark Boso Edition axle back exhaust is easy. First, make sure your vehicle is a 2015 - 2021 Subaru WRX or STI and that you have a Standard OEM Midpipe or REMARK Midpipe kit. The exhaust comes with gaskets and bolts, so it can be directly bolted onto the OEM or Remark mid Y - pipe. Just follow the standard installation procedures. When it comes to maintenance, since it's made of high - quality 304 stainless steel, it's fairly durable. However, it's a good idea to regularly check the bolts and gaskets for any signs of looseness or wear. Clean the exhaust tips with a mild stainless - steel cleaner to keep that burnt - blue look. Remember, this product won't work with aftermarket exhaust systems, so double - check your vehicle setup before installation.
