You could also try unplugging the PSE cable in the engine bay. This is straightforward and ensures the PSE is always on, e.g. with no auto cutoff at speed. If you're going to the OPC just plug back in again.

On the 981 series, it is a vacuum that operates the louder exhaust setting and the water cooling system valves are also operated by the same vacuum source.
So if your car is the same, you need to cap the exhaust vacuum tubes else you will stop the water cooling system valves working correctly.

Nigel99 My understanding is that it won't invalidate your warranty, however if something in the area of the modification was to fail as a direct result then this wouldn't be covered. 

Not entirely accurate. The extended warranty contract specifically precludes fitting non-Porsche approved parts without first obtaining written consent. So it can void warranty because the contract is breached . By the same token, the vehicle may also fail the 111 point PC check when the time comes to renew.

Hi Guy's not sure why this post has raised so much an interest again as I first raised the post in 2016, anyway I had a Porsche switchable exhaust fitted in 2016 to my 997.2 C2S (DFI engine) and am really please with the sound, on start up the noise is loud and then it switches over to quiet mode which I then have to select on again, the louder exhaust note then remains open from approx. 0 to 35 mph and then closes until approx. 45 mph before it reopens. Inside the cab you cannot notice much change, but if you open the windows or let some drive your car or ask a friend to listen outside of the speed times quoted there really is a noticeable difference from the standard exhaust noise. So in summary I am very pleased, I have heard some of the after market exhausts fitted and they are far to loud in my opinion unless you are an 18 year old boy racer.
