Cobra, Sounds like a drastic move.
I'm not aware of any airbox changes from '04 to '05. With stock gearing and can, any throttle increase above 4K RPM generated some intake honk. With the TOR can it's more difficult to hear and regearing requires a bigger throttle increase, but it's still there.
You might try removing the tank and the lid of the airbox and see if any sound deadening changes were made.
