Default Valve Controller on .2 GTS

Many fellow 992 owners have installed a valve controller of various brands (cargraphuc, kies) and general consensus from my research is the 992 owners with no PSE, the exhaust notes are roughly 50% louder than stock. Then those that have PSE say there is no difference or marginal sound increase which doesn't make it a worthwhile purchase.

Can any 992.2 GTS owners that has a valve controller installed chime in?

I'm about to pick up mine and was hoping to get some feedback first.

I have PSE on a .1 and the controller makes a big difference.

I am uncertain you have correctly described how it works. You might want to research it.

I have the M-Engineering stage 1 tune that allows the valves to open up 100% at idle. I love the sound and get many compliments on it. Can turn it off for long trips and early morning departures. It was a great "perk" to the tune.

This.

As someone less experienced with loud exhausts but wanting something more than the stock PSE that my wife, neighbors, and I don’t find too obnoxious, for now, I found the controller to be just right. The tone is not that appealing but it does provide more volume.

M-Engineering is definitely caters to my needs more (disable A/S/S, etc), too bad it is not available for .2 GTS yet.

I think we might be confusing how it works for the 992.1 v. how it works on the 992.2GTS. If you are talking about the 992.2GTS, you might want to limit this thread to narrow your question and avoid the many positive 992.1 responses you will receive. There is also currently an ongoing thread about how the controller works on the 992.2GTS so you could also post there.

I've edited this thread title to reflect and will search more, thanks!

ive along with many have confirmed. once the car is warm and pse is active the valves stay open 100%. so putting a valve controller on a .2 s or gts with pse would only be useful for when the car is warming up

I reached out to Kies and they confirmed for .2 GTS, the sound is only noticeable on start-up in normal mode. If you drive in sport/sport+ mode, the PSE is practically fully open and thus would not notice any difference. This confirms with real world experiences.

Thank you everyone & @APB-BOLO

Not accurate on my 992.1 GTS. When warm and PSE on forcing the valves 100% open with the controller improves sound volume:

On the Porsche 992 911, the Porsche Sport Exhaust (PSE) system does not simply force the exhaust valves 100% open when activated. Instead, it varies valve position dynamically based on several factors, including:
  • Throttle input
  • Engine load
  • RPM
  • Drive mode (e.g., Normal, Sport, Sport Plus, Individual)
  • Vehicle speed
  • Exhaust gas temperature

Key Details:

  • In Normal mode: Even with PSE "on" (valves open), the system may partially close the valves under light throttle or cruising conditions to maintain comfort and meet noise regulations.
  • In Sport or Sport Plus modes: The valves open more aggressively and stay open longer under load, giving a fuller exhaust note. However, they still vary with conditions, not just flip to 100% open at all times.
  • Under full throttle or higher RPMs, especially in Sport/Sport Plus, the valves typically open fully to reduce back pressure and enhance sound/performance.
So, while PSE enables louder exhaust and a more aggressive tone, it's not a simple binary switch — it’s an active system designed for a balance of performance, sound, and regulatory compliance.

If you want them always 100% open, some owners install a valve controller or perform a mod (e.g., vacuum line modification or software tweak), but that’s not how the factory system operates.

read the OG post. This is for a .2. Which the valves react different than the .1. I also had a .1

Yes, the Porsche 992.2 911 with Porsche Sport Exhaust (PSE) functions the same way in principle as the 992.1 — meaning:
  • The valves do not stay 100% open just because PSE is "on."
  • Valve position is still dynamically managed by the ECU based on throttle input, RPM, engine load, gear selection, speed, and drive mode.
  • In Sport and Sport Plus modes, the system opens the valves sooner and keeps them open longer, but still modulates them depending on conditions.

What’s New in 992.2?

While the core operation is the same, the 992.2 introduces hybridized powertrains in some models and updated software, which may slightly tweak valve behavior to align with:
  • Regulatory constraints
  • Emissions optimization
  • Hybrid integration (on hybrid models)
  • Enhanced sound tuning algorithms
But the principle remains: PSE = dynamic valve control, not a constant 100% open valve.

If you’re looking to have full manual control over the exhaust valves on a 992.2, you’d still need an aftermarket valve controller, just like with previous 911 generations.

the only manual control you get from a controller on a .2 is to have the valves open when it’s warming. Or if you don’t have pse (all S and gts come standard with this). Don’t have a .2? I do and I bought a controller and returned it as it was useless outside of the warming period. I have real world experience. It seems you do not. You are outside your lane on this one friend. I’ve owned two .1’s and now a .2. When the car is warm. The valves stay open 100%. At an idle. The valves are not the same as the .1

I'll agree with most you said except I'm not your friend.
