i think smoked tails on a silver car would look good....i'm slowly shifting my thoughts on smoked tails, after doing my own....i'm starting to think they'll look better on a silver or white car, not so much on a black car....i think those tails would look pretty clean if you smoked them...

 

Looks really nice!! I'm about to do the same for mine...
