ᐅ Soundproofing a soil stack pipe running through the open-plan kitchen-living area

Hello dear forum,
About two weeks ago, my family and I took over our new single-family home from a developer near Lüneburg.
Now that we are slowly moving in and the kitchen will be delivered soon, we noticed that a soil pipe in the exterior wall of the open-plan kitchen might not be properly soundproofed.
Above the kitchen is our bathroom. When we visited the house during the shell construction phase, I noticed that a soil pipe runs through the exterior wall from the kitchen into the foundation slab.
The pipe first goes down vertically about 20cm (8 inches), then horizontally about 70cm (28 inches), and then vertically again into the foundation slab. I seem to remember that the pipe was white, and something about it being a “sound-insulated pipe” was mentioned. From my research, it could be a Skolan pipe.
The pipe is partially wrapped in a red casing and fixed with a nail strip – which probably increases sound transmission, right? Also, I’m quite certain that the horizontal section is just a regular gray PVC pipe (HT pipe) and not a white, sound-insulated one.
When flushing the toilet upstairs, it sounds like water rushing through the entire wall down in the kitchen. Could this have been better insulated? And would you consider this a defect?
Looking forward to your opinions!
Best regards

The wall is currently plastered. Would the Armaflex then decouple the pipe from the plaster?
And would the angles of the bends (as far as I know, 2x 45 degrees) possibly need to be eased? You won’t really know how to do it until the wall is opened and you can see the condition. Normally, the pipe should already not touch the plaster and/or the wall at all—without the pipe clamps—so it wouldn’t need decoupling. Also, you need enough space to wrap a 20mm (¾ inch) thick mat at least halfway around the pipe. By the way, Armaflex cannot be plastered over. In that case, welded wire mesh or something similar has to be installed.

In our dining room, the downpipe is installed in the exterior wall. It wasn’t possible to do it differently in our case.
With insulation using mineral wool, we don’t hear anything. Neither when showering nor when flushing the toilet.
