Using this Remark axle back exhaust is quite straightforward. First, make sure your vehicle is parked on a flat and stable surface. If you're installing it yourself, you'll need basic tools. The exhaust directly bolts on to the OEM or Remark mid Y - pipe, so align it properly and use the included gaskets and bolts for a secure fit. As for maintenance, regularly check the bolts to ensure they're tight. Clean the exhaust with a mild stainless - steel cleaner to keep it looking great. Avoid using abrasive materials that could scratch the surface. If you notice any unusual noises or vibrations, it might be a sign that something needs to be checked. Overall, this exhaust is built to last, but a little care will go a long way in maintaining its performance and appearance.
