Cost of Catalytic Converter in 2010 Hyundai Elantra?

I need a catalytic converter replaced in my 2010 Hyundai Elantra. I asked a co-worker if he kneww about how much it would cost to have it replaced and he said it depends on the location. There is apparently 2 locations on most vehicles and one is easier access. Does anyone know if for my car? And about how much it should cost on average to be replaced? Thanks in advance and I'll pick the best answer within 24 hours or less.
