Congratulations! You're gonna love it, the black shadow edition is the best looking M2!
I picked mine up 2 months ago, couldn't be more happier!
I would recommend getting the MPE for it, with the carbon tips, they compliment the diffusor and the sound is out of this world compared to the stock exhaust.
I know it costs a lot, but you got to hear it in person to understand what I'm saying.
