Engine suddenly VERY loud. With Video...any help?

[ME30W]

I was cruising home from Gfest when all of a sudden my exhaust note got deep, distorted and was very loud. It almost sounds like I was running an open header. The car runs completely fine, I checked underneath and in the bay, nothing seemed out of order. It is just very loud.

I'm thinking I have some sort of large exhaust leak, or maybe a gasket? If it is any help, I have a remus catback and have had no problems with it since I bought the car.

Is there anything other problem that could be the source of the noise, other than a massive exhaust leak?

Here is a video: http://www.youtube.com/watch?v=6Jq8E1BwD8Y&feature=plcp

Get the car up in the air and check for exhaust leaks. I can't tell anything from the video, but an inspection with the car on a lift should find the source.
