That is completely worthless.

Without a muffler, if you cut out the entire black section of the rear bumper and then put a flat diffuser in it would help a little. If all you are doing is changing the muffler or putting in a short flat panel, it's not doing jack shit.
I understand where you're coming from; what we were shown was super basic and there was definitely science lacking. I consider it POC for those who said the stock muffler AIDED aero is all.

I don't buy pieces that don't have engineering...when a solution comes out with some science behind it, I'll look into it.

The car is probably entirely flat bottomed.
