Engine sound?

[T_11!]

I heard sound from some guys Treg fiesta last night and cant figure out what it was. Each time he blipped the throttle a sound would come from the engine (i think) that sounded like air being sucked in, anyone know what that may be? Cheers.

induction kit?????? that usually sucks air into the engine, passing through the flux capicitor first, and then out through the exhaust.

Engines need air to run dude!

That sound was air being sucked in!!

If it was really loud, then it was probably an open cone induction kit.
