Using this exhaust system is easy. First, make sure your vehicle is a 2009 - 2016 Nissan 370z. Then, follow the installation instructions provided. During installation, ensure all connections are tight to prevent any leaks. When driving, enjoy the clean and deep tone at all RPM ranges. As for maintenance, regularly check for any signs of corrosion or damage. Since the exhaust is made of SUS304 stainless steel, it's quite durable, but it's still a good idea to keep it clean. Avoid exposing the exhaust to extremely harsh chemicals. If you notice any unusual noises or a change in performance, have it inspected by a professional. Also, remember that the Advantex packing material has a high heat resistance up to 1200º F, but try not to subject it to unnecessary extreme heat.
