For those who have the 1.5L motor and have deleted the muffler, how bad is the drone? Also, I am having a hard time finding any pics of the underside to see how the pipe was supported since the hangers are part of the muffler. I am wanting to do this on my Clubman but want to make sure that when I go on a trip for several hours I am not wishing I hadn't removed the muffler.
