I've noticed that sound as well. I was showing off my G37 to a friend who has an 07 G35 and he asked about the exhaust sound. I started it up and it had that raspy sound for about 30 seconds or so. I wonder if it will go away with time?
mine didnt go away got it fixed once and now its back so im going to the dealer for round 2
