I did this too. Unfortunately I installed a shielded cone filter at the same time, so I do not know if there is any perceived performance gain from the snorkus removal alone. I think the humming noise is very annoying. I also think the intake sound at WOT is excelent. I am thinking about installing some piping in the fender wall to try and get rid of the damn vacume cleaner sound. I will post if I do this.
