It is possible that your catalytic converters may not be functioning properly, but before investing in expensive replacements, try conducting a few tests. Begin by checking the O2 sensor and inspecting the exhaust system for leaks around the catalytic converters (and near B2S2). Depending on how strict your area's emissions regulations are, you should also monitor voltage fluctuations in the post-catalytic oxygen sensor and perform the additional tests mentioned in a recent post on this topic.
