It sounds like you may have a clogged catylatic converter. They usually do not go bad on themselves. I would check to see if you have an underlying problem before replacing it. You can test to see if that is the problem by removing it temporarily to see if it drives normal without it.

You probably have a misfire that got so bad it burned up the converters. Yes, converters will often rattle when they come apart. I hope it's under warranty, if not, it's gonna be a pricy repair.

You could go to a muffler shop and see what they would price it out for. I would reccomend you first make the repair to whatever was wrong that caused them to go bad, or, you will be right back where you are now.
