Smell at all like rotten eggs? I have heard a catalitc converter on its way out can make that smell.

Yep, if it smells like sulphur/rotten eggs, you probably have a burned out catalytic converter that will have to be replaced.

could cause problems like that if it is restricting exhaust flow. Putting a pipe there would probably cause codes, due to the 02 sensor not reading

What did you use to pull those codes? They don't appear to be OBD2 codes...
