Any ideas?
The blue vacuum line is connected to this thing.
The orange wires connect to an "exhaust" button on the dash.

 

It goes to this BOV looking thing on the muffler:

 

PSE (Porsche Sport Exhaust) actuation perhaps? I'm sure that others that have the system will be able to confirm or correct that.

 

thats the porsche sport exhaust actuator and vacume plumbing, it opens and closes a valve in the mufflers, making it louder or quieter....

 

yeah you PSE only releases exhaust from one port in each tail pipe to muffle the sound, but when sport is engaged they all open up, That wire can be disconected to leave the exhaust loud even when your not in sports, thats what i did its been no prob. i could always reconnect.

 

Thanks guys
