After doing pipes and jets and not being really impressed, pulling the snork made the most immediately noticeable difference at the throttle. It does make the machine honk like a 2-stroke (for those of you who know the R5/RD 2-stroke carb honk), but if you know it, it's not a bad sound. It takes nothing to yank it out, just pull the seat and yank it. If you don't like what happens, just pop it back in. If you like the performance without, but you're concerned about the supposed water protecting properties of the top curve of the snork, cut the bottom length off and snap the curved bit back on.
But at least yank it for a short ride to see what you think!
