I don't have any whistling issues, but with all of the conflicting reviews.....you will absolutely have to cut on a 2014. I read the reviews that said no cutting, but there is no way to avoid it. The plastic piece between bumper and grill will have to be cut. I started with a hole saw and ended up cutting a rectangle out to get it to fit right. Not a big deal, just don't waste your time. Cut out enough to fit the entire top of the bracket through the plastic piece and you'll be done in no time. I like the look now that it's done, but wouldn't do it again.
