I've got a Supersprint Street model on order and it should be here in about 10 days. Supersprint in Tyler TX orders them from Italy once a week, on Thursdays, 7-10 days to get to States and then shipped from there. Allegedly a 2 decibel sound increase, 7 HP, 2 ft/lbs. $2500. plus install. However, my 09 X6 3.5 is so quiet I can't even hear it.
