It could be the cammo, but it appears the entire rear fascia is different from the Stingray. The normally black portion is straighter across the top. The rear fender now wraps around to the back showing what looks like ~3 inches of color body on each side, where the Stingray has none showing. That could also be cammo foam under the cover. Certainly, the bulge in the upper rear fascia is foam under the vinyl cover so it's possible that the center exhausts are the only change. Has GM had to change the trunk to allow the center exhausts? Will the roof still fit back there? Will the Z06 go back to having a fixed roof for rigidity, making the center exhausts possible?
GOT to wonder that if other than the center exhausts and maybe taillights again are the only changes, how many Stingray owners will be buying aftermarket center exhausts and aftermarket or GM black section fascias.
