Four. There are two small ones in the Y- pipe that connects from the exhaust manifolds to the rest of the exhaust, These are sometimes called pre-cats0 and one larger one that's aft of the Y pipe, but before the muffler. This larger catalytic converter is actually two smaller converters. For the purposes of your problem, "Bank1" is the forward-most one, and Bank 2 is the rear. It's all one piece though, so you have to replace the entire thing.
