Jman84, could you please tell us what year your car is and what motor is in it. That may help us out here. The next question that I have is if you recent hit a pothole or something that resulted in the car bottoming out. I am assuming you are probably also noticing a bit of power loss too. I am thinking you have something that has damaged the exhaust pipe and this is causing the exhaust to become backed up and go through a restricted area. That sound reminds me of what an I4 engine sounds like when they use a really restrictive exhaust system. I think a good look underneath may tell you all that you need to know.

Jman84, you don't mention any lights on the dash that occurred as part of this (ie, check engine light, ABS light, etc). If you do have the check engine light, then please go to a local auto parts store and have them read the codes and then post them here. that will help us figure things out.

Barring all this being good, I think the next step is to have an exhaust shop take a look at the car and see what they say. Unless you somehow had a large pressure pulse go through the engine that damaged both cats or both mufflers, I would expect to hear a difference from side to side of the car. Once they start looking underneath the car, I think the problem is going to be pretty obvious.
