why do you want to make it xi anyways? x looks much better then xi from all angles the most you can do is put on led headlights on your 2016 civic and make it a facelift 2019 civicx as that was the most that was changed by honda lol. xi is a different design and a much bland by contrast.. you cant change that much in your car without major alterations thereby destroying the integrity of the car better to keep it as it is.
