Using your new Remark axleback exhaust is a breeze. First, make sure your vehicle is either a 2015 - 2021 Subaru STI or WRX and that you have a Standard OEM Midpipe or REMARK Midpipe kit, as this exhaust won't work with aftermarket systems. Installation is easy because it's a direct bolt - on to the OEM or Remark mid Y - pipe. Just use the included gaskets and bolts to attach it properly. When it comes to maintenance, keep an eye on the stainless - steel parts. Wipe them down regularly with a soft cloth to prevent dirt and grime buildup. Also, check the bolts periodically to make sure they're tight. If you hear any rattling or unusual noises, it could mean a bolt has come loose. Remember, for a complete cat - back exhaust experience, pair this axleback with a Remark mid pipe.
