I have been babbling about the sound aktor thats mounted in our cars and i disconnected it both in my Boxster and Cayman.
I have mentioned it before that something happens in Sport mode even with cars without PSE.
Its not the higher revs or the backfire, the exhaust note it self changes.
From what i know the left and right muffler aint the same and they dont have the same pipe length either.
My guess is that i has something to do with a different routing.
The easy way to test this is for owners with SC, disconnect the aktor and switch between sport and sport+
(only difference should be the backfire when you let go of the throttel)
And do it at crusing speed and you will hear the difference.
It doesn't matter if the PSE is on or of the difference is still there.
PSE in normal or sport+ does the exhaust a tad louder, in sport its Way louder.
Today in normal my Cayman transforms to a luxury saloon soundwise and sometimes thats realy nice
