Since then I actually upgraded to SRC system anyways.
I don't think it's the passage of the anything throgh the neck roll, it's the not-too-aerodynamic Scala unit mounted on the outside of the helmet that creates more wind noise. I could notice more noise on the left side of my Shoei RF1000 after I installed the Scala.
