Yes, I saw someone earlier in the thread mention they had the outer hood stripes, but never saw a pic of their Camaro post install, so don't know if they kept them or not. Not sure I would do it that way, might look too busy... but would like to see it to get an idea. Figure someone has to have done it.
I also would consider doing this and adding a matching rear deck and spoiler stripe down the center at roughly the same width of the insert... that might look nice. Something like Angrybirds, extended all the way across the truck and spoiler as well. Looked nice, the pinstripe definitely dressed it up.
