I was wondering what is the difference between the PSE Exhaust tips and the 991 S Stock Exhaust tips?

Are they interchangeable, meaning can somebody use the stock tips with the PSE installed?

Thanks much for any information.

 

The PSE tips have different baffles inside the tips. Don't know how much different they make the sound, but are supposedly engineered specifically for PSE

 

AKA "Porsche Tax"

 

The stock S tips do not fit the PSE muffler.

 

Incorrect, they are identical from a fit perspective. The baffles are the only difference, aside from the PSE tips being a little bit shinier.
