Default Air Foil

Those who have installed a throttle body air foil, did your intake get louder? When I installed mine, the intake noise doubled. It sucks super loud now. I thought maybe the K@N filter was cracked, but it's in good shape. I checked the whole intake system for leaks and none were found.
I'm not really complaining it's loud, it just seems weird that a simple air foil will create such an increase in noise. So did this happen to anyone else?

I guess some of you did, and others not. It's really loud outside the car and I can hear it inside if the door is open or window down. It really did double in sound. I'm probably going to take it back off just to see if it goes back. I don't care if it's loud, I'm just making sure it's not a leak somewhere.
