HOW MANY CATALYTIC CONVERTERS ON A SE 3.5 AND HOW DO I KNOW WHICH ONE IS BAD?

2007 Nissan Maxima • 120,000 miles

My check engine light is on, had it tested twice and am being told by one place that it could be dirty gas, bad vacuum leak, or catalytic converter, treated the gas, cleared the code, drove about 40 or 50 miles and check engine light came back on. My mechanic says it is shooting a code for catalytic converter. How many catalytic converters does this car have and how do I know which one is bad? Thanks!

There is only one.

What is the trouble code?
