Using your Invidia Gemini cat back exhaust is easy. Just install it according to the standard procedures for exhaust systems on your 2007 - 2013 Infiniti G37 Coupe. The exhaust hangers are already welded onto the OEM locations, so it should fit right in. When it comes to maintenance, regularly check the gaskets and hardware for any signs of wear or looseness. You can clean the stainless - steel parts with a mild soap and water solution to keep it looking shiny. Also, avoid driving through deep water or extremely dirty areas as much as possible to prevent damage. If you notice any unusual noises or performance issues, have it inspected by a professional mechanic right away.
