Also - do I detect lift-throttle burbles???!?!? Saweet! I perfectly fine w/ this sound so long as this package is lighter, and has clearly more torque than the e9x v8. Lack of torque, high weight, which lead to poor mpg,... kept me out of the e9x. Let's hope the my M4 has a dash of 1M!

I'm sure it has a blowoff valve. It actually sounds quite sinister on the S63 - looking forward to hearing it on the S55.
