US Spec Exhaust Sound
Here's a quick video my 992 4S (US car without exhaust particulate filters). First is without PSE and second with valves on. I believe the max revs are 4K when the car is parked and cold (hence hitting the limiter).

This sounds significantly better and louder than the EU exhausts.

I personally like the sound. No it’s not super aggressive but it has a nice character with no droning and some nice burbles and pops. And being a 3.0 liter six I think makes it all the more impressive.

The sound outside is somewhat misleading. There’s a bit of a racket inside due to increased in piping sound through the symposer. It can get old quick.
when our good friends at Soul performance come out with a sport cat system, I’ll probably have to take the symposer out or obstruct it a little bit. It’s not about the loudness but about the quality of what’s coming inside the cabin.
for instance, on the 991.2 it was easy to tell if the car was in loud mode with PSE, now not so much. Perhaps a matter of taste.

I am very pleased with the noises made by my US Spec 992 PSE. It's downright civil compared to my no muffler Alfa Romeo 4C Spider and other cars that I have had in the stable.

Let me also add that when I test drove the car... the downshifts cause a significant amount of "pop" that I didn't expect in a new "dumbed down" version of the 911 as some would describe it.
