Using this Remark axle back exhaust is quite straightforward. First, make sure your vehicle is a 2015 - 2021 Subaru WRX or STI and has a Standard OEM Midpipe or a REMARK Midpipe kit, as it won't work with aftermarket exhaust systems. For installation, simply use the provided gaskets and bolts to directly bolt it onto the OEM or Remark mid Y - pipe. It's designed to be an easy process.
When it comes to maintenance, since it's made of high - quality T304 stainless steel with a high - temperature matte black coating, it's fairly durable. But it's a good idea to regularly check the bolts to ensure they're tight. If you notice any signs of rust or damage, clean the affected area gently with a mild stainless - steel cleaner. Avoid using abrasive materials that could scratch the finish.
Keep in mind that this exhaust has a muffler delete straight pipe design, which gives it a more pronounced sound. So, if you live in an area with noise restrictions, make sure it complies with local regulations. Enjoy the improved power, torque, and the cool Subie sound this exhaust brings to your ride!
