so good news and good news -
got my car serviced today and the exhaust tips were in so i picked those up $26 a piece. they look just like those posted above. will have pics once i get them installed (waiting on gloss black m3 badge).
other piece of good news is that they have another set of 4 in stock at Irvine BMW. So if any of you are local the service guy told me to tell you to drop by and they're yours. good luck.
