Drove an N54 last night, I am sold and will be selling my car here pending approval from the Boss Lady.
Amazing machines.

Do you have any plans for exhaust? I keep going back and forth... Need to find another local it to hear how loud it is while driving!
The best sounding exhaust is the PE exhaust and they have figured out how to emulate it with your stock exhaust. I will be doing it sometime this year. Basically you drop the catback and cut open the top of the mufflers then take out some of the packing and put header tape over the perforations in the exhaust then weld it up. Easy and is supposed to sound great, not to mention cheap!

Interesting! I will be very curious to hear your car after you do it!
FYI the Xdrive also has an extra set of cats over the rwd for some reason. I would put a DP on if I wasn't still in warranty. VRSF makes a nice 7" FMIC too and it is pretty cheap. The mods you need to do to these are minimal and they make a big difference. I love the handling, the only thing I plan on doing is an M3 rear sway bar and subframe bushings. That should correct almost all of the understeer from the sounds of it.

The stock exhaust isnt restrictive at all? No neck downs or strange transitions? Otherwise that would be cool if you can just mod the stock exhaust if it comes in a good free flow platform.
Nope, stock exhaust is changed just for sound purposes only. Dual 2.4" (with a few neck downs but not bad) the whole way. DP gains 10-20hp from ditching the cat. That is the only worthwhile exhaust mod really for performance until you hit 500whp. With a hybrid turbo it would probably be worthwhile to ditch the mid pipe and secondary cat.

Lovin all the info! Now with Rosey having a 335xi, the more info you share the better. So I have not done the Alpina flash because I am having trouble finding the latest software data files for the diagnostics software to communicate with the car on Windows 8.1. I might just make a windows xp mv image and be done. When are you installing all the goodies?
