IIRC there was a post a couple of months ago, where someone found the valves on their own on the 997 PET so ordered them and they worked. Link to comment Share on other sites More sharing options...

Are you sure that's what the vacuum tubes are for? I always assumed they were to detect accelerator off overrun and hence allow for more pops and crackles. Surely just turning off/on could be done electronically on ignition start without this complication? From what I understand the butterfly valve in the exhaust pipe is always open The vacuum is created when the engine is running so closing the valve when in normal mode . The option of the switch in the car is to sports mode the pressure drops opening the valve again so the shortest path is through the open valve bypassing some of the baffles creating the sound the method of opening and closing of the valve is mechanical so not quick enough to match the throttle response, you would need an electrical servo for this. As the pressure drops with engine speeds this varies the valve opening hence the difference in sound as the valve is slow to close this causes the pops with throttle lift If it's was either on or off with ignition then you would have the option of normal or sports Which in effect what you do if you just fit the exhausts with no vacuum tubes Link to comment Share on other sites More sharing options...
MIkeyv60 Posted March 13, 2017 Report Share Posted March 13, 2017 I have found some fitting instructions, i can see why it take 6hrs http://cf-design911-3.datadial.info/uploads/pdfs/Instructions_98104420004.pdf Link to comment Share on other sites More sharing options...

I pick up my s/h PSE tomorrow, but i have just realised that the console switch he has is for a Cayman and the Boxster one is different. I think I may start with the cheapskate option 4 for installation which is: - Install the pipes but do not install the switch/electronics/vacuum tubes etc. I should be able to get this done locally for £100 or so. This then gives me an always on PSE without the extra pops and crackles that go with the ECU update. I can then see what i think and maybe have the full install done at a latter date if I'm not happy. There are a few people on planet9 that seem to have done this and actually prefer this installation as you get the exhaust raspiness/noise but don't get the 'obnoxious' farts/pops and bangs Link to comment Share on other sites More sharing options...

The labour element was £480+vat so that's not 8 hrs. I bet they would quote more if I asked them to configure my system Link to comment Share on other sites More sharing options...

Anyway I'm hoping I like the cheapskate install, but should have the option of a full install if I feel it's worth an extra £750 or so. Link to comment Share on other sites More sharing options...

I'm delighted that every clip/bolt/wire/tube/bracket/seal and clamp is included so if I do decide to go for a full install at least I have all the bits Link to comment Share on other sites More sharing options...
