The 992 carrera 2s lack lustre sports exhaust system.

Hello I'm new to this forum and the Porsche Club and I was looking for some help and advise. I have the 992 carrera 2s purchased it new in August 2019. so far so good. we have had a few issues with the battery which have been address and a couple of other things that were put right, so as far as the car is concerned its great. However I'm disappointed and i don't get a buzz out of driving the car which is fitted with the sports exhaust system in black. Unfortunately MY Porsche sounds lame there is no excitement in the exhaust note, there no rasp not even an occasional pop. Im used to owning cars that do have a sports car sound. I think my 718 sounds better. So what can i do is there an after market system that can provide the rasp and the sport car sound whilst still being road legal. is there any and help available or advice any info would be most welcome.
Many thanks Dave
 
Have you got Sports Chrono or Sports Exhaust?

You might need to push a button somewhere to get the full sound.

I think it's Sport plus on mine and that shows in the speedo window. YMMV.
 
Hi Tim92gts
Now that's an interesting point to which i actually don't know the answer yet. on the sales invoice it states Sports exhaust system and on the equipment list it states four tract exhaust system with twin dual-tube tailpipes. looking at the rear of the car there are only 2 large black tail pipes showing so I'm guessing these are just a cosmetic cover tail pipe. As for a push yes i do have have a switch for the exhaust options indicated by a picture of twin tail pipes it illuminates when i switch it on or its comes on automatically if I'm in sports mode. The choice then is to turn it off which never happens. In my opinion there is so little difference between on and off it really makes no difference to the pitch or rasp of the exhaust this sports exhaust which was an additional costed option of £1844 inc VAT there is a school of thought that says i should have saved the cash as the standard exhaust possibly could have been the same or better. I need to find a solution
Many thanks for the thought.

Agreed, there's not much difference in sound with the sports exhaust on or off. Combination of turbos and the particulate filter I guess. An aftermarket exhaust will invalidate your warranty and as you've already found that's worth keeping.
 
Rear engine car with exhausts at the rear and moving forward, means you tend to leave the sound behind. It's always much better at full chat from behind than from within the cabin. [;)]

Peter, I'm not sure an after-market exhaust would invalidate a non-exhaust related claim under the factory warranty, although it would undoubtedly become a problem when Extended Warranty kicks in.

Well I wouldn't want to argue an engine issue under warranty with an aftermarket exhaust fitted, Clive [:-]
 
That's a fair point, Peter. [;)]

Strictly speaking Porsche would need to prove an exhaust was directly responsible for engine failure and this might be difficult. However, from a practical point of view, why take the risk? Best to avoid potential conflict for, if there's one thing guaranteed to spoil ownership experience, it's anguish and argy-bargy over warranty. [:(]

I took out a 992 C4S yesterday for a test drive from OPC Preston and the sports exhaust was noticeably different when switched on. I quite liked it because it was not too loud for me ( I am of a certain age!!) and it certainly wasn't as raucous as the one fitted to my 996 years ago. That was far too loud.

I guess if you want what I would consider a 'boy racer' loud / popping exhaust you will have to go after market.
 
I have it on my car and do notice the difference. However, to pops and bangs are not there, it’s just a deeper note than when switched off.

interestingly Rory Reid did a video on youtube about the noise regulations and it seems that from now on cars will have to be quieter. so it’s not just petrol particulate filters that are having an impact but EU noise regs. Seems also that adding an aftermarket exhaust could become a problem as if it’s noisier than the regs allow it could fail the MOT?
 
Hi Laurence71
for a performance car the exhaust not is very diapointing. I understand about sound behind the drive would not be the same as a front engine car. However I’m surprised that the heritage of Porsche could not get a better sound out of one of three high performance cars.
As for the EU noise regs. It’s not inhibiting Maserati, Ferrari, Aston etc. Am I right in thinking the new Porsche 911 GT3 has a new exhaust to match the car? Which is more of a performance car sound.
Thanks Dave

I am also of the older generation it’s not the boy racer cans I want on my cars. I’ve owned TVR,s now that’s loud. I chose the 2s over the 4 because I preferred the drive better that’s just my preference. The 992 is a great drive and change the setup for wet mode is just like driving the 4 really positive.
My last car was the Maserati 470 GTS when you started the engine it never failed to make you smile. Unfortunately you just don’t get that with the 992.

with the window open the sport exhaust sound is definitely present. It is not so loud inside the car as the 991 sports exhaust sound was. You will also find as the mileage increases it seems to get louder.
 
As a heads up, the 'Backfire' only happens when the 'Mode selector' is in [Sport] Mode. In [Sport Plus] mode, the car is meant to be giving you all performance [:)]

Hope that helps.
 
Hi and thanks for the menu. Its not very often that i drive in the normal mode. I find the wet mode with a few changes in set up very interesting in fact its very impressive. I drive in sports mode all the time and when able i will use the Performance mode, but that's no so practical on a short run but i agree the sound is better even with the window closed. Yesterday with the roof down i drove in sports and then in Performance modes I asked my passenger to compare the answer was Performance was very slightly more raspy, but not a really noticeable
difference. I do take your point that the sound might improve with mileage and my mileage is low at this time as I've not been out much since the lock-down started. yesterday i did get a bit of burbling in the exhaust in the Performance mode not a lot if you weren't listening for it you would probably wont notice it. In the sports mode there nothing much of a sporty note to speak of. I would just add that i was driving in manual mode and not hanging about.
Thanks for the info
 
David, you could always go back to the Porsche dealership and have the switchable exhaust system fitted ! Rather costly for a bit more noise. If you have only 2 exhaust tailpipes then you have the switchable already fitted, if 4 then you don’t.
 
Val, I think he has the switchable system already.

Dave, I agree with you. Having come from a few 911's the latest versions are the quietest exhausts so far. I haven't yet heard mine "bark" as it were on down shifts and in fact I am convinced it is broken. It just isn't a fruity as a GT3 or a 991.1 GTS, because they are naturally aspirated they just sound better. However my 991.2 GTS was worse than my 992. I will say, 1000 miles in and I can hear a slight difference when the Sports Exhaust is on, (it's much deeper on idle). But unless you spend £3/4K and invalidate your warranty I'm not sure there is a way to get a better sound.

One thing I did notice now that I can push a bit harder on a run in engine, the noise sounds very good at high RPM in the cabin!




 
Hi I have now completed a massive 3K miles sad i know, but I’m getting out and about a bit more now. The car is still lacking that smile factor, i leave the sports switched on all the time. The only time I do get a slightly better sound is if i drive in Manual performance mode and push. Then i do get a little noise But its still nothing really to write home about, and besides you don't really want to drive in that mode all the time its not practical.
I did think about changing the exhaust but having read the comments its not such a good idea the Warranty would be my concern. I like everything about the car its especially brilliant when its raining and you have the car set the car up in wet mode thats really impressive. Just lacks the performance car sound That I’m used too.
