That also depends on the age of the car, early catalytic converters were mostly publishitystunts as they changed the polution but didn't actually lessen the impact to the enviroment.
I had a truck that had the cat replaced with smooth pipe and I belive that was an over all improvement and "green" modification since I got more miles per gallon.
