My v35 coupe has the fujitsubo legalis-r exhaust (no intake mods)
After listening to all the youtube vids, I would say this clip gives the most accurate sound if you can ignore the "burbly/popping" sound... the start-up, idle and revving (exluding the burble/popping) sound virtually identical to in the flesh.
The other thing is that it sounds nice and quiet in the cabin, which to me is a good thing.
