Using this Cobb cat - back exhaust is straightforward. First, make sure you have all the necessary tools and the new hardware and gasket that come with the product. If you're using a stock j pipe or downpipe, don't forget to get the GrimmSpeed adapter. For installation, since it's an intermediate - level job, you may want to have some basic automotive knowledge or get help from a professional. When it comes to maintenance, regularly check the TIG - welded joints for any signs of wear or damage. Clean the quad polished tips with a mild stainless - steel cleaner to keep them looking shiny. Also, listen for any unusual noises which could indicate a problem. If you notice anything wrong, have it inspected as soon as possible to ensure the exhaust continues to perform well.
