Using this Cobb cat back exhaust is straightforward. First, make sure you have all the necessary tools and the new hardware and gaskets that come with the exhaust. If you're using a stock j pipe or downpipe, don't forget to get the GrimmSpeed adapter. Installation takes an intermediate level of effort, so if you're not confident, it's a good idea to get help from a professional. When it comes to maintenance, since it's made of 304 stainless steel, it's quite durable. But it's still a good idea to check the welds and connections regularly for any signs of damage or looseness. You can clean the quad polished tips with a mild stainless - steel cleaner to keep them looking shiny. This exhaust is designed to last, but proper care will ensure it performs at its best for a long time.
