sounds like your cat is overheating, that is most likely the cause of the sulfur smell.

Space, don't worry about it. It's the sulfir thats in the gasoline. Nothing you can do about it, and nothing's wrong with your car. I brought mine to the dealer cause I was getting that very rotten egg smell out the tail pipe, and after they checked it, they said it was fine. Also, I just stared working for a SAAB dealer, and the other day I drove a 01 9-3 turbo, and it smelled like that too, when I got off the car. Believe me, there is nothing wrong with the car.

spacecowboy,

Try using a better grade of fuel.
Some gas has more sulfer content then others.

Stations like Sunoco sell gas that is lower in sulfer. Give them a try, you should get better gas milage and the problem should disappear.

Perhaps Shell fuel can work too.

As far as I know, stations like BP and Citco have a tad more sulfer than the other big names. Id also stay away from the private "mom and pop" gas stations.
