I am not sure about actual performance gains.... but it does sound pretty cool... lol.. and I don't usually think like that... haha.... but I really like to hear the intake hum.. reminds me of old "listen to the four barrell kick in" days... whoooooooooerrrrrrrrmmmmmmmm
I just slapped a cone filter right onto my intake, no tube.. BUT, I truly think torque would be a little better with the correct length tube.. it does like to wind out more now though.. I like screaming (sound, not speed...lol) up dunes at 5000 rpm...
