Vehicle Type:
Cayenne (9YA) including Coupé variant
Engine Type:
DCB/DCBE = V6/3.0 liter/250 kW (340 hp) = Cayenne
Restrictions:
ONLY approved for vehicles FROM a certain production date (week/year) (depending on exhaust variant
(WITHOUT Petrol Particulate Filter (PPF) and body shape)!

Information:
Vehicles WITHOUT PPF: from 34 / 2018
Coupé vehicles: from 09 / 2019
Retrofitting
Figure 1
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.
