Just picked up a new-to-me 2021 X5 M50i in Davit Grey. Figured I’d finally make a post.
Spec & Background:
- Davit Grey Metallic
- White custom Milano leather interior
- Executive Package
- Bowers & Wilkins sound system
- One previous owner
- Picked it up at 29,000 miles
Current Mods / Changes:
- Front lip installed
- Carbon fiber steering wheel trim
- Magnetic carbon fiber paddle shifters
- M1 / M2 button upgrades
- Carbon fiber mirror caps + fender trim (non-X5M badged — avoiding up-badge cringe)
- Coded via OBD + BimmerCode (custom ambient lighting setups)
- 11-mode exhaust flap controller (plug & play)
The ambient lighting paired with the Sky Lounge + B&W setup completely transforms the car at night — easily one of my favorite parts of ownership so far.
The exhaust controller has also been a solid addition. It’s simple plug-and-play, but makes a noticeable difference when you want something more than the stock exhaust. Definitely adds extra character.
Planned Mods / Next Phase:
- H&R sport springs
- Spacers: 15mm front / 20mm rear
- X5M-style trunk spoiler. I’ll likely go with one that’s gloss black to match rear trim. This way I could avoid the paint match hassle. Any plugs for this piece would be greatly appreciated!
One of my biggest gripes is how the factory quad exhaust sits tucked behind the OEM casing. I’ve seen people add on exhaust tips but hate the diameter size of these and I laugh at the fact that they look like googly eyes. Has anyone else found a simple solution? I believe the easiest way to solve this, while also providing a sound upgrade, would be:
- Resonator delete
- X-pipe setup
- Vibrant Ultra Quiet resonators
- 3” inlet → quad 4” tips
Power Mods – Need Input:
The N63 in this platform already puts a smile on my face and honestly comes with just enough power. For the size of the vehicle, it moves incredibly well — every passenger I’ve had in the car is genuinely surprised by how quick it feels and how much it digs. I’ve had 4 fully grown men, along with 4 sets of clubs in the boot and draggy had my launch at a 4.1.
Although, that said… I’m already itching for a bit more.
I’ve been looking into:
- GTS Black RaceChip — seeing some solid claims, but not a ton of real-world data for this platform
- FEMTO unlock + tune — seems like the proper route, but also more involved
Trying to figure out if it’ll scratch the itch or if I should just commit to a full tune. However, the Femto unlock sounds like a hassle…
Conclusion:
Overall, absolutely loving the car so far. It’s outstanding for a daily driver. It’s a great balance of comfort, luxury, tech, and performance — but like most of us, I’m already thinking about what I can do next.
Photos below — appreciate any feedback and insight. Thanks yall.
Cheers!
