How have you modded the airbox, i chopped the inner wing side off mine and it's quite loud with a standard panel.
Honestly the standard paper element will be louder than a pipercross filter. No one has got a gain from a aftermarket filter. I got one because you can wash it and use it for years without replacing. Works out cheaper in the long run

Works out cheaper in the long runi'm not expecting to get gains from aftermarket over standard, just noise and longevity. i know the pipercross are designed to be quieter, what about k+n?
