^Would you be interested in the Meisterschaft? I just got a pretty good deal from SonicMS out in cali and I just got the pipes installed but didn't install the wiring yet.
So far the exhaust sounds almost like a stock E60 550i (little deeper but not as high pitched) with the valves fully closed. I'll be installing the wiring on Monday and cant wait to hear it with the valves open.
I manage a hotel and come and go at all hours of the night so it's nice to have the option to make it quieter so I don't disturb customers at 2 in the morning.
