I had these decals custom made during the summer by Spacep0d. He made them the identical size, design and color as my other bike. The sets he has on his site are a reversal of the colors and I wanted an exact match.
Here's a link to his site. These decals are super high quality -

Mine were custom one-offs so they cost more, but his standard versions are very affordable.
It is one of my favorite mods to my 300. It looks great and completed the bike to me. And I love having both bikes match even more. They both have Yoshimura fender eliminators too.
