Driving with a bad catalytic converter can cause all sorts of problems to the engine as well as the exhaust. High back-pressure can damage exhaust manifolds and manifold gaskets. Another common problem is when material from a failing converter is blown into the muffler. At best this can cause an annoying rattle. At worse the muffler will also be ruined.
