Using this Invidia Gemini cat back exhaust is easy. First, make sure your car is parked on a flat surface and the engine is cool. Locate the OEM exhaust system and use appropriate tools to remove it. Then, install the new exhaust by aligning the hangers with the OEM locations. The included gaskets and hardware will help you secure it properly. When it comes to maintenance, regularly check the hangers and hardware for any signs of looseness. Clean the titanium tips with a soft cloth to keep them looking shiny. Avoid using harsh chemicals on the exhaust as it may damage the stainless - steel construction. In case of any issues, consult a professional mechanic.
