The video is a good, but not great representation of the sound. It could be because it's a laptop mic, but it does sound a little more high pitched than the live sound. I'm guessing that it might help for video chat...?
Anyhow, I can see how it would not be for everyone. All and all I love the look and like the deep tone, especially on start-up. It will never sound like a V8, V10, etc; but I definitely wouldn't use the "R-word" to describe it. If I picked up any power in the mean time, cool. If not... meh.
Haven't had anyone try to race me from hearing my upgrade (I'm not into street racing anyway). However I do get more people asking what kind of car that is, etc more often. They sound more surprised than before when I tell them it's a Hyundai.
