Mystery part
#16
Notice the black rubber 'tee' on the gray solenoid. One of the vacuum lines goes to the left muffler and the other goes to right muffler. Those lines are covered w/ the stainless steel braiding when they pass through the inside fender well to each muffler area. They are there to protect the nylon lines from abrasion and temperature.
If a vacuum line is still connected to the source you might hear some hissing. Better yet put your finger or a piece of paper over the disconnected vacuum line(s) you found. If there is vacuum you'll feel it and/or the paper will stick to it. If vacuum is present you simply need to plug those lines up w/ some sort of plug.
Since you've been in this state for years I suspect all is good.

Here's a pic of the solenoid w/ the electrical connector/harness & vacuum lines attached from a 996. It's the same parts for a 997 and the location is as well.

Bingo....here it is
Looks like the 'tee' is gone and they plugged the hole
So last stupid question/assumption.....did cars w/sport chrono plus package not come w/the PSE button? I'm assuming when it was in it was activated by the the 'Sport' button

Sport Chrono equipped cars w/ factory installed PSE don't have a button. The vacuum ports are controlled by the DME. It always in the 'loud mode' w/ the exception of a speed range of approx. 18 to 27 MPH in which its in the 'quiet mode'. I believe it's a Swiss noise abatement law.
If the car didn't have Sport Chrono than a 'Exhaust Logo' button is used to activate the PSE.
