I keep hearing a slurping and whining sound from inside my car while I drive. I remembered I also have heard a whine from the rear of my car. Here is a video of the whine.

It's pretty hard to hear, my camera doesn't have a great mic. Also, starting the car, the exhaust sound kind of overtakes the whine... I thought revving it would increase the sound, but nope. Lol.

Just in case anyone is wondering, it's stock except for a JLT cold air intake and a Flowmaster Delta 50 cat-back. (less info)
