Yeah this seems to get worse when it's colder outside which leads me to believe the BMW PE I have is out of alignment. I was backing up about a month and a half ago and swerved to avoid some idiot behind me, backed the tip right into a curb and pushed the whole exhaust to the left. I was able to straighten it out on the hanger, but I guess I knocked it out of alignment more than I thought. The noise appears to be coming from just after the header.
