Meistershaft Muffler with SR (Connecting Pipes) and Black Cover Shield
It says E90 on the plate but I have been running it on my E92, fits fine. No problem. Imo the tip size fits better because it's not sticking out as much, give a much cleaner look.
Used, shows minor wear on one of the tips from rubbing against a diffuser (see images below)
Price: $1500 picked up in NorCal
