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.

What’s the difference between the MAD catback and Dinan? There are not a lot of video clips comparing stock vs catback exhaust sounds or one brand vs another.
I was initially considering a JB4 piggyback tune but after I discovered that I can’t remove the speed limiter or use the bolt-on mods fully, I figured BM3 would be the best. Do you have any experience with either tune?
Also, I was thinking of getting a backup/second ECU DME to clone my original OEM ECU DME. Then I would bench unlock the backup ECU and use that primarily. Then swap the ECUs whenever I need to get maintenance done at the dealership. I read that dealerships will flash the ECU which will lock it again during maintenance services and I don’t want to pay to get it bench unlocked every time I service my vehicle. Are my concerns valid? Is there a better way to do this?
Another reason I wanted to keep my ECU DME pristine is that I want to protect the resale value as I plan to work my way up to a X3M and then a X5M later on. I love the B58 engine for its reliability but jumping through all these hoops to get the DME unlocked seems like a lot of work compared to pre-2020 model years.
Thank you again!
