For a N/A 4-cylinder, I think it sounds pretty good. Definitely a little too loud for a daily ride (my $.02), but it'd be fun for at least a few days.
And while I'm not suggesting a resurrection of the "4-cylinder Fart Can Craze", Ford would have been on to something if they had these engines back then.
Thanks for posting the video though. I'd never try it on my own, but was definitely curious how it would sound.
