Best stealth mods?

Not 100% sure stealth you mean is like invisible from outside or murdering out badges etc on body panels,
but how about these for starters?

Racing Line makes strut brace from machined aluminum. Looks nice and maybe marginally improves steering feedback, but maybe I'm imagining it.
Good thing is that it didn't ruin ride quality.

Intake system. Carbon weave on Eventuri's look way better, but this one from GruppeM was 2/3 the price and uses K&N filter which is a lot easier for me to source replacements and cleaning kit. How much difference does it make power wise? Um, I wish I could say it's night and day but no... barely noticeable. With the hood open the filter makes some nice induction noise, but you won't get to hear it at all while blasting.

This is probably what you meant, a quattro badging on the lip spoiler. I liked the quattro logo the pre-face lift's grille, so tried one in glossy black (OE part from e-tron sportback).
About 6.5inches wide and an inch tall, fits perfectly on the spoiler. But I'm still on the fence about the outcome...
It looks perfectly stealthy when the light is low and pops up when the sun hits the car. Maybe the width were slightly wider and didn't look squished?
Let me know what you guys think.

Yes, that’s the kind of thing.
I was looking at 034 Motorsport and their various chassis upgrades

I like the concept, but would make it larger and wider. It looks a bit too stealthy!
