Using this midpipe is easy. First, gather all the parts included in the kit: the 3 - piece exhaust unit, V - band clamps, donut gasket, gaskets for the 2” exhaust section, and the hardware. Then, attach the midpipe to the downpipe using the factory - fit flange. Next, connect the sections of the midpipe using the V - band clamps. Make sure all gaskets are properly placed to avoid any leaks. When it comes to maintenance, since it's made of T304 stainless steel, it's corrosion - resistant. But it's still a good idea to clean it regularly with a mild automotive cleaner. Avoid using abrasive materials that could scratch the surface. Also, check the V - band clamps and gaskets periodically for any signs of wear or looseness, and tighten or replace them as needed.
