Notes:
With the sports exhaust system, the signal for activating the flaps in the rear silencers 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 behaviour of the vehicle are not affected.

The sports exhaust system is also available straight from the factory for new vehicles by requesting

optional equipment "0P8 – Sports exhaust system (Brushed stainless steel tailpipe)" or "0P9 – Sports

exhaust system (Black chrome-plated look tailpipe)".
