Just installed the Exhaust Meister on my 2012 650ix Coupe. Removed trim tabs, pulled carpet out from under rubber seal on the trunk, removed the luggage tie down and unplugged the control line to the vacuum control and plugged in the Exhaust Meister and then attached the ground. Voila valves are now controllable via a remote....Then I helD the remote up to the homelink mirror and programmed the right and center button to open and close the valves.
I would be hard pressed to say it took longer than 10 minutes....$130.00 for a fun little gadget that really helps the exhaust note...I LOVE TOYS....
