997 on/off for PSE - Page 1 - 911/Carrera GT - PistonHeads UK

I've had the switch disabled on my 997's PSE so it's permanently on, as I didn't like the way the system cuts out between 30 and 50 (or whenever). Does anyone know if it's possible to install a switch so I can turn the thing off for motorway driving if I feel like it, but I still get full noise by default all the way through the rev/speed range? Thanks. BTW I'm based in London so it'd be useful to know of anyone who's local if at all possible. Cheers.

http://www.carnewal.com These guys do a remote controlled such that allows you to do exactly that. I keep meaning to order one myself!

Last time this was discussed, people seemed to be unsure that the Gen 2 had the speed-related cutout. Interesting to find someone who says different. Might have to fit my switch after all.

Sorry to appear ignorant, but could someone explain what the PSE is and does, I gather it relates to the exhaust, and is it fitted to a 997 turbo?? Thank you in anticipation

Thank you in anticipation The Porsche Sports Exhaust (PSE) can be ordered as an option on most models in the range and is equipped with valves which remain closed (normal exhaust sound) until the remote switch on the centre console is operated and then the valves open to give more of a sporty exhaust sound - in other words what they should sound like.

Thanks for the responses. Appreciate it. I'm sure the 997.2 had the quiet range feature as I remember it from driving the car, and also the OPC confirmed it. Will check out the carnewal switch. V useful. Thanks! jm. PSE = Porsche Sport Exhaust. It's an optional extra that transforms the sound. Not sure what the deal is with Turbos. They have an entirely different set up and sound for obvious reasons so I don't know if there's a Porsche option to add a more tuneful exhaust note. I do know that there are a lot of very good specialists that can help though.

Hmmm I'm not sure it 'transforms' the sound on a Gen 2. Seems to make more of a difference at lower revs so perhaps the valves close again at certain engine speeds. The difference is small but worth having IMO.

This Carnewal remote switch sounds interesting - £100 to keep the valves open 100% of the time without having to press the button every time you start the car - sounds reasonable. Have anyone here fitted one ? - it says it takes 10 minutes to fit and is reversible so I assume it just plugs in somewhere. Is that correct ?

I've got the Sharkwerks bypass, which helps the sound on the Gen 2. I've got the Carnewal switch, but haven't bothered fitting it.

That's another option. It makes no sense that the valve closes between 25-40 mph (as seems to be suggested) I'd rather have it working all of the time before deciding whether to go for the Sharkwerk bypass. They say it's a 10 minute DIY job to fit. As you haven't bothered I'm guessing it's not that straightforward.

It looks ok to do, just haven't been suitably convinced that it'll make any difference. It's a case of plugging in and then earthing one wire.

Thanks. Had a look into this earlier and the other option is just unplug the cable for the PSE and zip tie it out of the way. Think I'll try that first - although you get the extra noise all of the time it saves you having to press the button and I dont think it's loud enough to be a problem on motorways, etc (for me anyway...)

Yes, you pull the metal clip and unplug. Tried it during a Euro trip once. Didn't bother with cable ties. Cold starts are a bit loud and there's the risk of the PSE valves sticking after a while.

You can pull the cable and tie it away. That's what I did with my 997.1, and what I think the OPC did with my GTS. However I now want to be able to turn the sound off on occasion, so am after a switch to be able to do that. Just re-plugging in the cable won't do as the louder setting cuts out between 30 and 50. Plus one has to actively engage the thing every trip, which isn't a big deal, but I'd rather not if I don't have to. I'd rather have loud on by default through the range, plus a switch to turn it off on motorways and when the wife is complaining that the car isn't practical.

Just ordered, will confirm ease of fit and sound improvement. (no mechanical ability!) I also have no engineering skill at all, so would be very interested to hear how this goes. Hope it's an easy job for you :-)

Also interested to know. I disconnected the lead last night - 2 second job. Will live with it like that for a while and see if the noise is a problem on motorways otherwise I may try this solution as well.
