Ok so yesterday i was looking underneath my car at the muffler because I am going to get a new flowmaster muffler and noticed something behind the muffler, and I told my friend that the cat. converter was behind the muffler, and he said that is not possible, looked underneath my car and was confused on what it was, but still insisted that it was not the the cat. converter, so if it is not then what is it?
