Using this Turbo XS adapter is easy. First, make sure your vehicle is a Subaru WRX from 2002 - 2021 or a Subaru STI from 2004 - 2021. Then, take the 3 - inch catback adapter from the kit and align it with the OEM downpipe and the 3 - inch cat back exhaust system. Place the 3 - inch metal clad graphite standard exhaust gasket in the right position, held in place by the machined lip on the adapter. Once everything is lined up, secure the adapter properly. When it comes to maintenance, since the adapter is made of 304 stainless steel, it has good corrosion resistance. But it's still a good idea to check it regularly for any signs of wear or damage, especially after driving in harsh conditions. And always follow the California Prop 65 warning. Avoid breathing in exhaust fumes, don't let the engine idle longer than needed, service your car in a well - ventilated area, and keep your hands clean by wearing gloves or washing them often.
