Using your Remark R1 - Spec Cat back exhaust is easy. First, make sure your vehicle is parked on a flat and stable surface. Then, follow the included installation guide to directly bolt on the exhaust system. The gaskets and bolts are already provided, so you don't need to look for extra parts. When you start your car, enjoy the loud and aggressive sound that this exhaust gives. For maintenance, regularly check the Tig - welded joints for any signs of wear or damage. Since the mid - pipe and muffler are made of 304 stainless steel, they're resistant to corrosion, but it's still a good idea to clean them occasionally with a mild stainless - steel cleaner. Avoid using harsh chemicals as they might damage the exhaust. Also, be careful not to hit the exhaust on any rough terrain or obstacles, as it could affect its performance and appearance.
