30 DNB V2 stock pipe VS VRC unslienced pipe SOUND

hi all, Stock 29cc 30DN motor with the std pope and VRC for you to compare. The idle was a bit high on the tuned as you can hear but you get the idea. I did not detect any performance gains.... but this 29cc motor is in need of a service/ top end rebuild as a minimum. Next up I am thinking of trying my Taylor 35cc in it. :)
