Is anyone else getting frustrated with the lack of updates?
Exhaust system
The standalone AMG exhaust system is a twin-pipe system over its entire length with two catalytic converters installed directly on the engine and two on the underfloor. Two individual rear mufflers are installed behind the emissions treatment system to reduce noise emissions.
Exhaust flaps
Controlled exhaust flaps can be installed optionally as special equipment. The rear mufflers each feature an exhaust flap which, depending on the power request of the driver and the engine speed, are operated electrically and on a map-controlled basis by the engine control unit using two actuator motors. This technology resolves the conflict of aims in combining the emotional sound experience of a sporty driving style with restrained noise development under partial load conditions. The sound design has succeeded in producing the perfect synthesis of tangible dynamics and the typical Mercedes understatement. The engine sound remains pleasantly inconspicuous, and nuisance frequencies are effectively eliminated.
Did that help? I'm not sure it did.

Hello,
The C63 & C63 S comes standard with a Dynamic Exhaust System that has:
- 1 computer controlled flap that acts as a cross over between the two banks ofexhaust
- it is run by the engine controller and varies the opening/closing of thevalve based on throttle, mode and other factors.
C63 & C63 S optionally have the U78 - AMG Performance Exhaust System thathas:
- 3 computer controlled flaps (the one from the standard system and one on eachtail pipe)
- it is run by the engine controller and modes, etc
----> however there is also a button on the center console that the customercan turn on/off which modifies the exhaust note similar to the new GT.

"What is currently on the website is not the certification weight which is still pending from the govt...why typically the difference is negligible and has do with fluid weight....as soon as the cert weight is confirmed it will be populated on the site."
So that weight on MBUSA.com isn't correct. Thats some good news.
