The thread below explains it. On early Boxsters with the PSE option from the factory, there was no interior switch to control the valves. The exhaust was wired such that when the car went faster, the valves would automatically open. The early PSE had exterior shiny "sebring" style pipes that you could easily see from the rear. If you didn't get this option from the factory, many would just use metal cable wire to keep the valves open all the time, and this is fine as I'm not sure why anyone would want to silence the muffler, as even in the loud position, it wasn't all that loud. The 03+ PSEs sound better than the previous ones, as it had more growl.
On later PSEs from the factory (03 onwards), they got rid of the shiny exterior pipes, and so it looked like a standard exhaust from the outside except that the underside had valves and small pipes that couldn't be seen from behind the car. On these, there was a button on the upper console (shown in the thread below) that could open and close the valves at will. Honestly, the PSE is hard to come by now, and they don't drone, unlike most any other aftermarket exhaust (except the Dansk that I have as well as the home made PSEs done at muffler shops using the OEM muffler). If it were me, I'd keep the PSE and just get cat bypass pipes, but up to you to explore. You can definitely get a better sounding and crackling exhaust, but it will most likely come at the price of drone. Can you deal with that?
