I can't listen to that vid here, so can't say at the min.
I've driven it once without the covers on & tbh it's really weird (but kind of cool) hearing all the noises the engine makes. I didn't realise how how hot it gets in there without them on, until I got back in it & realised it was sauna-tastic !
sounds fairly standard to me, mine's a lot deeper, grunty sort of sound..
also the induction noise is right in the passenger side pod.
