Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

People I know with the electrics installed don't tend to use the switch at all - they want the beautiful sound all the time!

Is there any audible difference between the early type non adjustable PSE and the later type that you can adjust from the cockpit ?

Coverage and how to read this overview

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.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Sorry guys, im sure this is covered many times but please humour me. Is there any audible difference between the early type non adjustable PSE and the later type that you can adjust from the cockpit ? And where would you connect the early vacuum operated valves too ? Thanks

POST 2Original post

Post 2002 exhaust can have electrics or not but it sounds the same. Pre 2002 exhaust sound different. The post 02 exhaust has a much deeper note not as raspy.

POST 3Original post

What do you mean PSE is adjustable from the cockpit? I have it on my '03 C4S and don't believe it's adjustable.

POST 4Original post

Do post 2002 PSE's fit pre-2002 996's?

POST 5Original post

Fishman, The PSE can be installed with or without electrics, the latter option giving you a switch in the cockpit (which has an exhaust symbol on it) which enables you to switch the exhaust to an "off" (i.e. non PSE) position, for example, if you don't want to disturb neighbours/raise the dead when you are leaving early or returning late. Cost of installing the electrics adds about 7.5 hours labour (sorry - UK spelling!) to what should otherwise be a 2 - 2.5 hour installation (I think). People I know with the electrics installed don't tend to use the switch at all - they want the beautiful sound all the time! Regards Deeps

Thank you Deeps.

POST 7Original post

No problem. I have a 2002 C4S which I recently bought used, but (incredibly sadly), without PSE. I am currently looking at exhaust options, including PSE, because that's all I need to make the car perfect.

POST 8 / ORIGINAL POSTEROriginal post

deeps, I recently bought a PSE system to pull apart and look at as I am making sports boxes for the 996, I am modifying standard boxes to sport spec, I will be offering them on an exchange basis for sensible money, my intention is to let people try them and if you like them it gives me the green light to mod yours and exchange again, if you are interested please contact at [email removed] Regards
