Using this exhaust is easy. Just directly bolt it onto your OEM or Remark mid Y - pipe. The gaskets and bolts are included, so you can start the installation right away. When installing, make sure all connections are tight to avoid any leaks. For normal use, there's no special requirement, but try to avoid driving through extremely deep water or hitting the exhaust on rough terrain. To maintain it, you can clean the exhaust tips regularly with a soft cloth and a mild stainless - steel cleaner. This will keep the burnt stainless look shiny and new. Also, check the bolts periodically to ensure they remain tight. If you notice any strange noises or performance issues, have it inspected by a professional.
