If you have the V6 3.3L Supercharged engine you will have two catalytic converters. There is one on the drivers side towards the front and one on the passenger side towards the front. The drivers side would be MagnaFlow Catalytic Converter, part # MF49478, and the passengers side would be MagnaFlow Catalytic Converter, part # MF49477.

If you have the V6 3.3L normally aspirated engine you will have a total of 4 catalytic converters. The two in front on the drivers and passenger side and two in the rear on the drivers and passenger side. The MagnaFlow part numbers will be the following:

MagnaFlow Catalytic Converter, part # MF49997 (drivers side front)
MagnaFlow Catalytic Converter, part # MF49998 (passenger side front)
MagnaFlow Catalytic Converter, part # MF49480 (drivers side rear)
MagnaFlow Catalytic Converter, part # MF49479 (passenger side rear)

These catalytic converters are 49-state and Canada emission control standard approved. They are not California emissions approved.

The exhaust system for your 2004 Nissan Frontier Crew Cab V6 with 74-inch bed would be the MagnaFlow Stainless Steel Cat-Back Exhaust System, part # MF15866. This is a stainless steel system that replaces everything from the outlet of the catalytic converter back to the tailpipe.

I am also including a link to a FAQ page on catalytic converters.
