i have a GReddy Evo2 on my Accord and it's wonderful. (Note: my RPM ranges are for an F23A1, not a GS-R)
Car startup: You can tell it has exhaust.
Idle: Little to no sound
1K-3K: You get a "blip" if you hit the accelerator then let off being a gas wasting idiot. Not loud or high, very deep and low.
3K-5K:Very deep. People on the side of the road say "damn that sounds nice"
5K-Redline: My AEM intake drowns the exhaust out.
