I don’t think the PSE exhaust incorporates fiberglass, hence I don’t believe it gets louder or throatier over time. There would be no logical explanation to my knowledge. I suspect it is a somewhat natural thing us humans do, which is to attempt to explain our own “confirmation bias” on options that we spent money on.

You’ll notice a difference as the engine gets properly run-in/broken in. Folks with higher mileage 992s can confirm this from experience. I’ve received compliments on how my car sounds and people are surprised that it is stock. Then again, I am coming up to 30k miles.

only one way to confirm, people with PSE need to throw ipads in the backseat and set to recording 🤣

reckon the whole car ‘relaxes’ as the miles add up. A 911 takes several thousand miles to be broken in, seeing one that doesn’t get used much is just sad.

The change in sound and tone of the exhaust stems from the packing that is inside the muffler, which is usually a fiberglass compound. Typically the fiberglass in the mufflers/resonators breaks down some after use and the exhaust may become louder or change tone some.

My cars with GPF have definitely changed after being run in. So have my cars with regular cats. My first car with GPF is my 812 GTS and after about 3000 km and a few days running hard on the Autobahn, the sound has changed significantly. My Pista and 488 opened up nicely after tracking as well.
The exhaust does change, but you need to push the car a bit to get a good effect.

Not just relaxing, nor is it really being broken in. More like breaking down.
