I has to do with your Exhaust. Example: Two Exhaust tips out the back doesn't necessarily mean that you have Duel Exhaust, it could be a single exhaust that splits into two exit tips or a single muffler that exits in two pipes. A True duel Exhaust runs separate from the left and the right and runs all the way to the Rear of the Car. A separate setup like that would need two Catalytic converters, one for each side.
