I put a Toyo decal on my hatch window and an APR decal on the rear side window. I'm not sure if I'll want to keep them, so I didn't want to mess up my paint. They're not too flashy, and since they're silver they match the fill-in decals on the rear hatch also. I thought about putting the K&N and Invidia decals that came with my Intake
and exhaust on the rear side window too, but they're too colorful.
