You'll notice the valves - even if set to open with PSE activated - will close as you accelerate and then open again at a higher RPM range.

But with your valve controller, they can be open all the time with PSE, or closed, both via the console switch.

- Method A: The first method is a partial PSE override for those that simply want the ability to have the valves open 100% of the time. This will allow you to keep the factory PSE controls unchanged until the valve controller kit is activated. Once activated at the push of a button, it will override the PSE controls completely and keep the valves open 100% of the time. Then at the push of a button and you can revert back to the factory PSE controls to close the valves and have the car operate the valves as normal.
- Method B: This second method is a complete PSE override for those that not only want to open the valves 100% of the time, but close them 100% of the time as well to meet sound restrictions at various tracks. Factory PSE programming will not become active unless the valve controller kit is uninstalled from the car. Switching between 100% closed or 100% open will be controlled at the push of a button, no automated valve control is available with this method.

When you say "push of a button" in both methods, which one uses the center console button - Method A?

Here is a demonstration video to show how the valves are controlled from the factory with no valve controller:

You'll notice the valves - even if set to open with PSE activated - will close as you accelerate and then open again at a higher RPM range.

The high pitched and GT3 like sound out of this car requires blending the exhaust flow with an X-Pipe. To get the same level of quietness with the valves closed at the stock car requires an incredibly large and restrictive muffler. And then you have to have that giant muffler and that x-pipe fit in the same space on top of the rear diffuser. If it didn't have the areo...it would be more plausible just like the 981 generation. You win some, and you lose some. Realistically speaking the closest you're going to get to that kind of experience is to combine our high flow catted headers with our competition over axle pipes, bolted up to the factory PSE muffler. Maximum sound/aggressiveness with valves open internally bypassing the muffler but with the quality of the tone kept in check by the high flow cats. Then with valves closed it still goes through the giant PSE muffler and kills the sound.
Best regards,

Apologies if I overlooked the description of this very setup in one of your videos, but have you done (and posted) your usual street testing clip with the configuration of your catted street headers + OAP + stock exhaust?
Also, still waiting for someone to temporarily rig up a 981 PSE off the back of one of these just to see what we are or aren't missing. Fingers crossed. Hint hint. I think if it doesn't sound close to as satisfying as the 981 then a lot of us holdouts who have been waiting for some silver bullet to come along will start to move on with life and finally purchase something that's available now.

John - as someone who is after whatever is as close as possible to the 981 GT4/Spyder sound (save some of the crackle pop), I took note of what you've said here in bold.

So it would take a vendor to develop a similar exhaust system to the 981 GT4 or GT3 (on the inside) but that allows you to keep the center diffuser.

The problem is that if it works you lose the diffuser....another vendor tried a GT3 rear section and sounded great but again, you loose the aero benefits.

Yes I know this... that's why I specifically said temporarily. If it sounds 981esque, then the task is out there for a vendor to somehow recreate that sound working around those difficult conditions. I never said it would be easy, or even possible, I just think many of us would feel a lot better knowing what the car sounds like with a 981 PSE bolted up.
I never set out to recreate the sound of a 981 on my 718 Spyder, this engine has its own song and I personally love what it wounds like especially with an x-pipe rear system, for me there is no reason to want a 981 exhaust note on these cars...

Using method B you are 100% disabling the PSE function & Button from the get go and now valve control is done 100% of the time with activation of the SOUL Valve controller (push of a button... on the SOUL remote).
Hope that helps

The console button is only available if you use method A and only functions if you have the SOUL Valve controller disabled. The factory system is active and will open and close as designed, but if you activate/turn on (push of a button... on the SOUL remote) the valve controller, you are effectively disabling the factory PSE and PSE buttons function... Leaving the system fully open. But with SOUL Valve controller deactivated/off the PSE system works as no modifications were made.
Using method B you are 100% disabling the PSE function & Button from the get go and now valve control is done 100% of the time with activation of the SOUL Valve controller (push of a button... on the SOUL remote).

Which is longer - 2021 model arrived in port until arrival at dealership (CARB & EPA clearances) or Soul order placed until arrival? That IS the question.

There's so many factors with things being delayed these days because raw materials are a real issue in almost every industry. I mentioned these shortages sometime ago in another thread and said that If you want anything soon you best get it ordered and paid for now. Manufactures will have no choice but to raise prices due to raw material constraints/allocations/increases and the aftermarket performance sector is just starting to feel the pinch, not to mention the EPA's men in black knocking on their doors now too!
