The factory PSE retrofit should be available within the next few weeks. Love this system, seems to have more "popping" sounds than previous PSE exhaust systems. PM me if you want an update when they're available.

 

I have a 991S and LOVE LOVE LOVE the PSE. No sunroof as I didn't like the aesthetics of it when I saw it in person. All up to you, but the engine sound is just amazing with PSE

 

Get both...you open your sunroof to really hear PSE!

 

I know you have heard enough but what the heck ... how can I not comment ... I have the PSE and the sunroof

PSE - like others say this is just an amazing option, the gurggles and pops are just amazing and it not only occurs when shifting down but also when you shift up you get that extra gurggle (is that even a word??)

I sometimes test myself to see if it is all in my head and I leave it off and try to pretend I didn't order it ... it just doesn't give you that extra incredible sound ... sorry I know $3,000 is a lot for an option but I really feel this one is one of the best options to buy. It takes a great sounding engine and makes it even better.

Sunroof - if you don't use it, don't get it ... I like it and open it sometimes just to hear the PSE
