Question 2021+ GLS 63 AMG Stock Exhaust Not Loud Enough vs Resonator Delete?

Did anyone purchase a 2021+ GLS 63 AMG and find the stock exhaust not loud enough? I am worried because I heard the 2021+ models pump sounds through the speakers. (Excluding 2024+ models).

I am also worried because I for the past few years have been collecting and noticing sounds of specific cars, this one, and yes although you can hear it from outside as a regular pedestrian, it isn't necessarily going to rumble between skyscrapers nor inside bridges and under tunnels. I mainly listen for it and it sounds like it's intentionally designed for the DRIVER + anyone maybe a FEET away from car.

Is there enough or not enough pops, bangs, crackles. (I need those like every single second, is there a way to produce more?) (How do I create more pops, bangs and crackles? Is there ways to get more than factory without intrusive mods or tunes?). Or does the car need a exhaust mod. I can't do or won't do a muffler delete. Anyone have videos of a 2021+ GLS 63 with only a Resonator Delete?

I have sat in one before at the dealer and they started it up and I know it sounds absolutely crazy it was so freaking loud the whole showroom started looking. I called it 'The Dragon' in my head. The startup sound may be too loud, even, but it's only a startup sound, and it was inside an enclosed showroom.

And then, driving off, but when the car started to idle and low rpm I noticed it sounded just like a regular car but nicer. I drove it off in Sport + mode and it did have a sound and you can definitely hear 'whoosh' from turbos. Not too sure on crackles only drove it 5 mins around the block.

POV Video Stock:


What I Need Car To Sound Like: (Can anyone say if this is what their exhaust stock sounds like or no?) (If not what do I need to do to make it sound like this)
