2022 540i Exhaust Input Needed

Sorry, I know there's a ton of these posts. I've read them all. I think I finally almost have the exhaust sorted for my car and looking for a final bit of input.

This is my daily, goal is OEM+. Still loads of warranty left on this thing (its a CPA), so no tune, dp, etc for the foreseeable future. Will probably do a Dinan CF intake with or without Turbo Inlet depending on warranty concerns.

Trying to avoid drone and anything TOO loud - just want a cleaner, deeper tone and a bit more volume. Cost is not a factor. Imagine I like to play hard, but also want something I can valet in Boston for a nice dinner without looking like a trash bag. Final 3 options seem to come down to:

1) Valvetronic Cat-back (yep, I know about Alibaba equivalent) - Really leaning hard this way, love the valve control, worried its going to be insanely loud running w valves open. Seen tests on stock tunes hit 107-110dB.

2) Dinan Axle-back - love the fact that its Dinan, probably my favorite tone in the samples I've heard. Not crazy about it deleting the factory valve and I'm worried its gonna be too loud 24/7 with no way to quiet it.

3) Mad Axle-back - Love that it keeps the factory valve and I can add a valve controller. Maybe not my favorite sound of the 3, but there's not a lot of samples out there.

I've watched everything I can find on youtube and IG. Remus is always back-ordered to hell so I'm not really looking at it. Any input would be greatly appreciated.

You won't be disappointed with your choice. I did somewhat the same but, I added the Remus mid pipe. It's nice to be able to control the exhaust flap.

Yes it does, if you still want a little deeper tone. No drone.
