The coupler cover is the same as the factory, which is why I offer the boot type which is much easier to deal with. Lastly, regarding headers, I have seen so many variants in height, its not fair to blame the box.
I just want to clear the air on any issues you may have so others don't avoid purchasing for the wrong reasons. I urge people to call me with any questions before creating a stir on the forum that leads to the incorrect conclusions.
