I might be in the minority here but on the Challengers at least I don't care for the removal of the Dodge lettering. Just seems naked and too plain with nothing there.
With that said I can envision it looking good without the Dodge lettering on the Chargers. The racetrack inspired oval taillights encompass and complete the back end better so I believe it wouldn't look out of place without it like on the split taillights of the Challengers. You might have to be the trailblazer here, lol
