You should be able to find it in the parts diagrams at http://realoem.com/bmw/showparts.do?...89&hg=18&fg=20
. It wasn't attached to my car and may have been eliminated for the LCI models, but my original muffler still had provisions to install it. The PE muffler also has the attachment point. All you need is the rubber piece and the bolt to attach it.
I can't say if it would help or not, but it's a low cost option.
