I believe it the valves open and close based on the driving mode you're in. I'm not a 100%, so I'll let someone that knows chime in.

On PSE cars with M-eng tune, the valves open either by pressing the exhaust toggle or by going into sports/+ modes.
On non-PSE cars, you don’t have an exhaust toggle, but your dealer can easily activate the PSE toggle function via assigned button (this will actually make your non-PSE exhaust a little louder). If you choose not to do that, you can still have valves open by going into sports/+ modes (normal mode will close the valves).

I did it for these reasons:
#1 Eliminate the "farts" at sport mode (abhor the farts)
# 2 eliminating the Auto- on/off engine (also not a fan of the ***)
#3 eliminating the cold start (another unnecessary juvenile/rude aspect - is Porsche stacking their focus groups with 9 year old boys?)
#4 easy to install/uninstall
And got these for free:
Revving >300O RPM at stand
more power boost
On the cons, I personally did not get any shaking at lower RPM, don't care about warranty void very much, have had no data log issues and am fine with the occasional loss of traction - it's not the most friendly sideways driving car because the grip limits are pretty high but I very much enjoy the well controlled oversteer when the conditions warrant it...
Not familiar with the heating up the spark plugs / premature failure issue but will cross that bridge when/if necessary.
