Sound "symposer" vs PSE
I have a 991.2 with PSE.
When I optioned the car, I thought the switchable sport exhaust was an excellent idea allowing me to go loud or quiet as I choose. Something I didn't know, is that PSE creates all that noise for the outside world. Not so much for the cabin. Yes, it gets a little louder inside, but most of the magic is on the outside.
I recently drove a non-PSE car and was surprised to hear a much more pleasant, inside facing, exhaust note when switched into Sport mode. I would say the non-PSE car was louder inside the cabin than the PSE car.
The cabin noise is created by the so called "sound symposer".
My question is, is that only built into non-PSE cars? If that's true, is there any way to retrofit it into a PSE car?
As far as I know it's a resonator tube between the intake and the rear seats. Or something like that. What do I know.

The only way to get a decent sound in the new cars is to weld a pipe from the downpipe (pre cat) that enters the cab. That will help you hear the car with the only trade off being a very mild smell.

They all have the sound symposer. Your observations are similar to what was posted in a nice video by Nick Murray comparing two 991.2s w/wo the SE. If you want to a louder sound inside, you can go with some aftermarket systems like tubi etc. They will make the car much louder, both inside and outside. Not pleasant. My 991.2 without the SE sounds very nice in sport mode. Not as nice as the old NA 3.8 but can't be helped. The SE in the 991.2 simply adds a little more sound and lots of burbling in sport mode that some (like myself) absolutely dislike.

Wow. Opening yourself up to a lot of liability with a suggestion like that on the internet.
