There was an LT1 swap into a chop top GT at the 2014 Daytona show (was only there for a while) that had 4 tips in the area originally taken by the license plate. I don't have a picture but maybe somebody else does.
I really liked the way the exhaust looked. Unfortunately he had to relocate the license plate into the tail lights and I didn't really like that. So just like the image above, if it had to have a license plate it would look goofy. But yeah, it looks sick without one.
