Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

hi, on page 123 of my owners manual it mentions a rocker switch for turning on/off this function. Does anyone know about this? it must have been an option; the manual isn't explicit whether standard or option. just curious about this, cool or lame? I've read a lot about the 991 having different exhaust modes. I never realized our cars had this, too. thx
PSE is an option. I put one on my car but left off the vacuum hoses and electronics as many do.
I have one. It's my favorite button. It's nice to be able to tone it down/up when its appropriate.
^^^ ditto^^^ my favorite button. At about 3k rpm the sound is deep and throaty. It was about a $3k option and worth every penny IMO
Option, very cool and desirable. If you don't have it, you can get Fister cans, or Gundo Hack for about $300 and get a very similar sound all the time.
