Well, I don't understand what is going on then, because my car sounds completely different now from when this video was made a few weeks ago.... 2nd, 3rd, 4th, and 5th sound perfect. 1st has no sound at all and seems to run out of breath slightly around 6500+rpms...

Video of when my car was running correctly below:
