+1 The G's exhaust is very nice, but only people that are behind the car or outside the vehicle get to enjoy it. Even with the windows rolled down, not much I can hear. What I hear more of is the engine and though the VQ37VHR is a wonderful engine, past 5500RPM, its coarse, unrefined, and ignorantly loud (not in a good way). The N54 on the other hand is buttery smooth
and I just want to rev it more and more to listen to that beefy twin turbo inline 6. My dad drives a 528 with the N52 and that thing is even smoother than the N54!
The power delivery from the N52 is so linear. Nevertheless, engine wise, BMW is still a step ahead of Infiniti. This is coming from a guy who used to love the G37.
