I think those are just exhaust covers, sadly. Kinda reminds me of what Lexus did with their previous ISF. I do like the looks but if it was actually functional that would be a plus.
Yeah for sure the quad tips definitely add to the luxurious persona. I am glad there was an option for the MKZ.quad exhaust setup sure does change things around along with that color which blends the piece around the exhaust tips in.
Is there something that could be sprayed or applied on to keep it from tarnishing or turning black? I thought I came by something like that.The integrated exhaust looks clean. My only concern is cleaning the exhaust tips once they become black. The painted bumper gets in the way and can be easily scratched.
