Rattling sound under car
I'd like to say it's coming from the front end, but I'm not 100% sure. It's happening when going over any lines, bumps, cracks, etc, and when the steering wheel is quickly turned from side to side while driving.

Rattling noise from under car
I have the same problem. From what I've gathered so far, it's the catalyst coated honeycomb meshes on the inside of the catalytic converter that have collapsed or broken apart, causing a rattle.

The only way to find out is to put the car up on a lift, tap each cat with a rubber mallet to see if they rattle, and check all the front suspension bushes/ball joints/tie rod ends for any excess play.
