Just make sure if you change the rear ratio, you change the front as well.

Depends what transmission you have.

If you have an auto tranny, your gear ratio is 3.55.
If you have a manual tranny, your gear ratio is 3.07.

First, you want to be certain that that's where the sound is coming from. If it is, you definitely should regear with a higher ratio as opposed to putting in new stock gears
