FWIW here is what my car sounds like with an external mic placed next to the license plate.

It does have a slight rasp at higher rpms but it's all personal preference.
I don't have any of my own videos shot from a distance, but this is a pretty good representation of the real-life sound with test pipes + MPE. Without resonators I'd say mine is maybe 10% louder with a touch more rasp.
