I took an incremental approach too. Step 1 - valves wired open. Step 1.5 (or 0) - back to stock. Step 2 - GPF gutted and valve controller. That was all done between delivery and a couple of weeks after my car got back from PPF. Step 3, about 4 months later - Soul Valved exhaust. Step 4 - ?

do these “steps” ever stop! I’m going broke reading this forum
So the way I understand it... if you want the higher pitch only and not much volume then you need an x-pipe muffler of some sort, if you want volume then OPF delete? A valve controller is a given must-do mod.
I've been a Soul customer from the start, with a 991.2 Targa GTS and now with a 718 Spyder. I had headers, cats and tips on the former and street headers/high flow cats, OAP delete pipes and valve controller (and of course, tips) on the latter. I think most would be satisfied with my setup, which is more throaty vice high-pitched, but that is with the headers/cats. I am debating whether to change it though since I want more sound (one of the few that could care less about neighbors, police, etc.) so I may go with the race exhaust (straight or resonated). Either way, Mike, John, Alex, and the rest of the crew will take care of you, via email or over the phone...you will not bother them!`
This is the exact same thing I'm doing next wk, as my Soul valved exhaust just shipped today! Keeping the GPF pipe on, and removing the Sound Symposer. I have great expectations. Plan to take a quick before and after video. I tried a GPF delete pipe alone, and decided it wasn't what I was looking for wrt sound.
You get 2 battery-operated keyfobs with the Soul Valve Controller and Homelink buttons can also be used; there are 2 methods one can hook it up based on preference.

can’t wait for your video, your 6 weeks ahead of me. Hopefully next week I get the valve controller installed (step 1)
Been running the valve controller for a couple months with the Sound Symposer in place. Not impressed with it always open. Honestly, The low-midrange sounds with the Symposer in place are annoying to me. I go back and forth, liking it one day, not liking it the next. I have it wired so it's either always open, or in stock configuration.

Would removing the sound symposer with the Soul valve controller help with what you are experiencing in the low-mid range (valve open)
IMHO, removing the GPF is mandatory first step to get you back to a “base” system.
Almost all that have forced the valves open report big resonance at low RPMs..perhaps that’s why Porsche programmed them the way they are.
Valves staying closed until 5000/3800 is fine for me doing transit miles…if I’m “on it” then I’ll be above valve opening. Transition doesn’t bother me at all.
Here’s the OEM GPFs, note the flat back plate exhaust fights through.
