To be honest, i was just testing the phone holder i got for my trackday tomorrow, but its ok video and kind of shows the sound of a standard airbox and a ITG, also you can hear the 5k kick now and again. Ill be back with more vids from curburough sprint track tomorrow, so sorry if this ones a tad boring
