Holes in the bumper will help any vehicle no matter the power level.

Think of the rear bumper cover acting as a parachute, scooping up air going by under the vehicle. Causing drag and reduced fuel mileage.

These "diffusers" are just an esthetic cover for the holes cut out in the bumper to complete a cleaner look rather than just having random holes cut out.

When I got dyno'd I didn't have it on there yet, but between the fans and my exhaust that's pretty much an open dp with a turn down the bumper looked like it was gonna rip off. Hahaha

Is There any difference @ 1/4 mile?

Never cared for the round holes in the middle of the bumper.

I ended up with slits, and while not exactly perfectly scientific, I did go from 135mph to 139mph afterwards.

How did you drill holes?

When doing this, did you have to support the space between the "slits"? I think I like this much more than the holes!
