Using this Invidia full titanium cat - back exhaust is a breeze. First, locate your old exhaust system and carefully remove it. Make sure to keep all the parts organized in case you need to refer back to them. Once the old exhaust is out, take your new Invidia N1 exhaust. The exhaust hangers are already welded at the OEM locations, so it should fit right in. Connect all the parts securely using the new gaskets and hardware provided. After installation, start your car and enjoy the new sound. As for maintenance, it's a good idea to regularly check the gaskets and hardware for any signs of wear or looseness. If you notice any rattling or unusual noises, it might be a sign that something needs tightening. Also, keep the exhaust clean by washing it occasionally with a mild soap and water solution. Remember, if you're using the factory downpipe, you must have a compatible catback adapter to ensure proper performance.
