if you google a little bit, you'll see that cat bypass pipes reduce the performance on cayenne turbos, however increase the performance on cayenne s. Maybe the turbo engine loves the backpressure...

MeanMachine is a glorious beacon of light

Canberk acutally its better on the CTT, as the cayenne turbo's dont need that much backpressure like Superchargers as an example.
