Notes:
In the sports exhaust system, the signal for activating the flaps in the rear silencer (NSD) comes from

the respective current map in the DME control unit. The driving status and accelerator pedal position, for

example, are decisive factors.

The sports exhaust system can be switched on and off separately using the Porsche Communication

Management system (PCM ⇒ Figure 1). To do this, select the menu "Car", then "Drive" and then "Exhaust

system".

The sports exhaust system is also active in the "SPORT" or "SPORT PLUS" driving modes.

The engine power and exhaust behavior of the vehicle are not affected.
