You are correct. Bank 2 is the left side, or directly behind the radiator in this case. R+R of the coverter does not require removal of the exhaust manifold. If you have the available tools, and everything goes relatively smooth, i'd say it shouldn't take more that 1.5 hours at most. You access it by removing the flex pipe from both bank 1 and 2 converters (you can leave the rear flange of the flexpipe untouched, the part that connects to the rest of the exhaust). These nuts are usually quite corroded, so i'd recommend getting new ones and new gaskets. You have to remove the exhaust manifold heat shield. The easiest way to do this (without cutting/scratching your hands a lot) is to remove the plastic cover on the radiator support, and the radiator support itself. Once that is out, remove at least the driver side radiator fan. This will give you a lot more access to remove the shield. You can remove the passenger side fan also, but this is a little more complicated to remove compared to the driver side. Next, remove the heat shield on the converter itself. Once the heat shields are off you should be able to see the 5 fasteners holding the converter and manifold together. Should be 2 bolts from the top, and 3 studs with washers and nuts from the bottom. Just undo these and it'll come right off. You'll need a new gasket for this too.
