Default Rear bumper cover question

Do the slits on either side of the rear bumper have any performance attributes or are they purely cosmetic?

I like to believe that they help with the airflow over the mufflers to assist in keeping them cooler. But, that may just be a figment of my imagination.

In a small way they may help undercar air flow,keeping pressure from building under the rear,couldnt hurt.

That is kinda what I was thinking they would do, just act similar to a rear diffuser.

So I guess its running extra cool since I dont have those heavy mufflers in the way? Right?
Or is it running below optimum temperature and hurting my performance?

They are there so you can see your highly polished stainless mufflers, of course.

I just have straight pipes, dont have the money for turbos and personally prefer a NA motor to FI or the bottle.
