I remember from the private viewing that it was only an aesthetic component on the bumper. The two mufflers are under the car, and don't even touch the bumper outlets, but are directed towards them.

Can anyone confirm with a pic?

 

yeah the tips are just in the middle of the opening, it's not attached. but i wonder if this is better since air doesn't flow around the tips

but if anything it's minimal i guess

Yes. Those "muffler openings" (don't know what the official names are) are really unique and cool looking.
