They do in fact come off. If u contact whipple they will 99% of the time send u new stickers for free.
^This, and I would recommend sanding the mounting pads on the blower to give the adhesive something to grab onto. Something like 80 grit, then clean them really well with thinner, or brake cleaner to ensure they are really clean. That is about the best you can do.
Whipple sent me a pair of stickers then I sanded the surface down like the other member did and then added gorilla glue. It stayed on with me for 2 years and then cbr respol had it my blower and it lasted with him to.
What? :??:
