I would reccomend Dinan over valvetronic.
But I would reccomend the MAD catback over Dinan.

Same with their downpipe, as well as their full intake, as I have all of that on my 2018, although I'm not 100% sure they make an LCI intake as mines pre LCI, but either way, if you want to hear the turbo you'll want the upper and lower intake bits.

I would also recommend MHD over BM3. From the research I did, although MHD is a little more conservative, the tunes they have offer much better daily driveability. I believe you also get more bang for the buck with the super license by comparison.

The heat exchanger I can't comment on, but Im sure it wouldn't hurt.

Keep in mind, since you have a 2022 you'll need the DME sent off and unlocked by Femto. There are rumors other tuners are beginning to figure out how to unlock the newer DME's, but so far at this moment that's all it is, I can't confirm.
