PSE?
- Thread starter c2s
- Start date
Afraid not. The ports exhaust is an extra and is not included with chrono plus. However if you want a sports exhaust having sports chrono reduces the cost a little.
I had sports exhaust on my gen 1 997 C2 which was worth the extra but not on my current gen2 C2S. Have driven a gen2C2S with sports exhaust and do not think it worth the money.
Enjoy the car

The four exhaust pipes are the same on the C2S whether you have PSE or not - i.e 2 large, two small as I recall. If the PSE was fitted as an option call any Porsche Centre with the VIN and they can tell you. You should be able to hear the note change even at idle. Not all have the separate PSE button on the dash. The other light that comes on with your Sport button is the PASM light to tell you that you are in harder damper setting mode! This can be de-selected separately. [

Going off at a slight tangent, about identifying spec from the VIN, has anyone used this site:

I got it from a thread on Pistonheads and it seems to work well. Type in your VIN and it gives a very comprehensive list of spec, code numbers and a description.

I have a pse and it works well up to from memory about 3500-4000 rpm after which there is no difference, no problem on track day noise metering. What was a shock was how poorly routed the metal braided vacuum tubes are to little diaphragm pots high in the inner wheel arches. They just float around the engine and exhaust pipes and the clips to the pots corrode badly. Take the wheels off and give them a good squirt of wax-oyl, since the whole area seems impossible to get at and is just asking for trouble.
On the 997.1 only the sports exhaust (option XLF) has different-sized outlets (outer ones are bigger than inner ones).
So if you have one pipe larger than the other on each side then you should already have PSE.
You can check the options sticker in the service book for 'XLF', but PSE is available as a retrofit so your car could still have it even if it wasn't fitted at the factory.
With PSE there are two exit pipes coming out of each muffler (one for each of the four chromed tailpipes), otherwise there's just one pipe and the twin tailpipes branch out from that one pipe. You can easily see this if you look under the back of the car.
Another way to check is to look in the engine bay, just to the right of the steering fluid reservoir (where it says 'only Pentosin CHF11S' on the cap) - if you see a little grey item with a brown plug connected to it, you have PSE.
If you have the Porsche warranty then PSE is your only option, anything else would invalidate the warranty (including the bypass pipe modifications offered on eBay).
If you don't have the warranty there are lots of aftermarket options but if you're only after sound the 997.1 PSE is pretty good.

hey thanks for your post its funny you should say this.
Now according the extras on the VIN no sports exhaust is fitted.
Yet I do have one chrome tail large at each end on each exhaust tip, also I have an I code registered to the VIN that porsche dont release to the public.
I telephoned them and asked why and got through to someone who I had to fax a copy of the sales invoice and logbook to porsche to prove I own the 997s.
He rang me back and told me the I is a retro fit code but he needs to dig futher to see what it means, sometimes next week as those are not available.
I am hoping its a sports exhaust either I have one or the S has a pretty mean standard exhaust system.

As I said earlier you can hear the change over at idle if you have PSE fitted. Just sit in it at idle and press the Sport button (as you don't have the separate PSE switch) If the exhaust note doesn't change then you don't have it! I'm still not convinced by this different size exhaust outlets being a sign of PSE fitted. I'm fairly certain every C2S has the different size exits. I'm over to my PC on Tuesday so will enquire there too if not resolved by then![]

On the subject of the PSE I'm still undecided on whether I should go for the PSE for the Gen II as a retrofit. I drove a GTS at the weekend and whilst at slower speeds I could here it burbling and sounding a bit throatier, the faster I went the less different it sounded. Has anyone disconnected the brown plug to see what difference it makes?
I was mixed on the GTS but to be fair Bournemouth traffic didn't help me get the most from it [] It does look good though especially with the aerokit fitted.
Cheers,
Simon

Hi TSC,
This'll never be a specialist subject for Mastermind but I assure you that the standard exhaust on the 997.1 Carrera S always has equal sized tailpipes (you can choose finishes but they're all the same size, I've copied a pic from the 997.1 sales brochure). Only PSE has the unequal-sized tailpipes.
There are a couple of reasons why pressing the sport button wouldn't make an audible difference:
1) The valve actuators on the mufflers are seized
2) The plug has been taken off the solenoid valve or the vacuum line is blocked
PS: The uneven-sized 997.1 PSE tailpipe trims aren't interchangeable with the standard ones. The PSE tailpipes only fit the PSE muffler, as they fix to the outside exit pipe, whereas the standard trims are a 'Y' piece and fix at the centre to the single exit pipe of the standard exhaust.
Never invite me to a party, I could bore everyone to death.

Tim,
I bow before your considerable knowledge.[] Still odd that the OP has the different size exhausts yet the the other info received via the VIN says that it's not fitted. So a retrofit by a previous owner?
If the plug has been taken off the solenoid it's in permanent "loud" mode, yes? Fairly easy to spot - if you know where to look![]
Personally, I would just take the car into the nearest dealership and get them to have a butchers!

Personally, having had PSE on 3 Porsches (Cayman & 997s), I think it is a total waste of money. At low speed it is muted due to German noise regulations and at higher speed one cannot hear the exhaust noise over the tyre noise.
