That was really rude for no reason.. I am pretty lost myself and looking up a lot of the terminology as this is not my profession. My occupation or hobbies aren't cars, however, I have been a BMW and have been a BMW owner for 12 years now and im only 33yrs. Therefore, when I saw the pipe on my drivers side of my 2012 X6 exhausting only on that one side , I decided to look it up. Don't judge others because were all obviously all here to learn... Im sure you just learned a thing or two... check!!
