I've read on here a couple vinyl makers make the black out strips that have a cut out so you dont have to remove the rear bowtie. But if you still want to remove it, take a heat gun to it then remove it with dental floss by "sawing it off" as it were. Then get the remainder adhesive with 3M adhesive remover. Theres a couple of threads on here that tell you how to do it in more detail.
