Using your new Remark Boso Axleback Exhaust is a breeze. First, make sure your vehicle is a 2015 - 2021 Subaru STI or WRX and has a Standard OEM Midpipe or REMARK Midpipe kit, as it won't work with aftermarket exhaust systems. Installation is easy - 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, keep it clean by washing it regularly with mild soap and water. Avoid using abrasive cleaners that could damage the stainless - steel finish. Check the bolts periodically to make sure they're tight. If you notice any rattling or unusual sounds, it might be a sign that a bolt has come loose. Also, if you plan to drive in harsh conditions, like very salty roads in winter, give it an extra cleaning to prevent corrosion. With proper use and care, your exhaust will keep giving you that great 'Bosozuku' style and loud, aggressive Subie sound for a long time.
