GTS 991.2 - PSE?

[GG33]

Sorry if this is a dumb question, but what is 'PSE' and how do I know if I've got it? I know it's exhaust related but not clear if it's a standard feature on the GTS.

Standard on GTS I think , "Porsche Sports Exhaust" you get a button on the right in the centre console which looks like 2 exhausts.
