Except the exhaust, I'm looking for more options for get a impressive sound that scared you. Sensational racy sound, you know. Comes from the engine, not from the exhaust.
So, I found out that a 2-wing metal fan made another sound than the 4-wings and the plastic fans. With the 2-wing metal fan: if you give gas, it's like a airplane that was running for a take off.

And now I hear anyone saying the ITG-filter give a really another, compared with the K&N filter, a weird impressive sound.
I don't know or this is true, and a ITG-filter is not really cheapass. Can anyone tell me more about that? Is the sound of the ITG impressiver than the K&N?
