What sound is this?

Which sound do you mean? The hissing sounds like a supercharger. The noise when he pulls away and changes gear sounds like a horse trotting
 
Could be ktr kit or a maxogen but then i am only guessing. When i put mine on (ktr) i was quite surprised how loud they are.
 
Sounds aftermarket induction but I doubt you'll find out which one.

Send a pm to the youtube channel?
 
He is over on cs as markcup too. I think it was a mic in the engine bay. Which reminds me I was meant to order one for Sunday :worried:
