Porsche sport exhaust switch
 

2008 Porsche 9114s with sport chrono: is my car pre wired for sport exhaust switch?

You are more likely to get an answer in the 997 section

I would be surprised. My '10 4S was not. I installed the complete PSE from the factory including the factory harness so it is as it would be if that was an option that was from the factory.
