I have seen several reports from those that drag race the 6th gen platform make a cover for that area or remove the lower bumper cover if the stock suit case is removed because they say it acts like a parachute. Most of those guys don't post on this forum...they are over at FB or IG. My opinion is, as long as you have some sort of mufflers back there I don't think it's a big issue. It's mainly for those with straight pipes or dumped exhaust.
