Ask them if they provide a package deal wherein a good lawyers services are provided for the lifetime of exhaust ownership.

Techart installed...
I had the PSE and changed it to Techart on mine 991CS.
Valves "off" sound is like something between valves on/off on the PSE.
In ON position it sounds like a V10. Very aggressive !!!!!
On downshift is just sounds just ............ !
Its working exactly like the PSE with factory switch on console , but it has its own control module which is connected to the PASM unit. This control unit from Techart make the exhaust valves more "active" and it opens even in "silent" mode if you apply throttle.
Techart gives warranty on this system which also cover the engine if breakdown is related to exhaust.
Picked it up today after WC 43 and 25 (took 10 working days). Several
on my way home for the sound.

So their system is made to be hooked to PASM as standard?
The exhaust marketing is horrible, their information is not clear. Their pricing is perplexing, is it because they are all low volume units?

I have a 991 2s with PSE
Dealer had exhaust system vacuum switch disconnected so exhaust was in sports mode all the time and very poppy and nice. After about 1000 miles a water coolant warning light came on - took car in to dealer who said warning was due to sensor on exhaust and have reconnected vacuum switch so exhaust now switches on and off normally.
The problem is - I can hear absolutely no difference with exhaust switched on or off through complete rev range and does not burble or pop anymore.
Is this normal????
I had an old 997 c4s with sports exhaust and that was very easy to hear the sports exhaust coming on and off.

I have been doing some research into exhaust for the 991 and I thought a topic that summarized what was available was in order. I am considering having factory PSE added to my 991 C2S or going aftermarket. I called the service department of the local dealer and he tried to talk me into a Tubi system so I thought I would start there. I see this as a living post and I will update the first post if it gets up some steam over time.

After I pointed out the Tubi price the dealer agreed that the PSE system made sence. That is likely how I am going.

Wise move. At least whatever you spend on the PSE will be worth something to the next buyer. That Tubi will only remove value off the car and will have to be rid of when you sell it. An Akra would be a different story.
