Yeah it's probably the catalytic converter. However, you might want to do a visual inspection and make sure you didn't get something plastic stuck to any part of your exhaust system. I once ran over a small piece of construction grade plastic sheet in my 350Z and it caught onto my catalytic converter and made all kinds of weird noises and smells. I had to go through all kinds of stupid gyrations before I got it all off and the smell went away.
