I'd recommend picking by other than vids... As pointed out,they are hard to make. They are also highly dependent on surroundings, ambient noise, microphone function and proximity/ location, whether the car is in open or closed loop, Internet compression, and speaker quality of the playback device.
Try to to hear them for real yourself, avoid drone, watch all the combinations and custom tweaks, and as pointed out a v6 will never sound like an 8.
