When I first bought my car it had an exhaust gasket leak. While getting that fixed it was discovered the cat was plugged up. At the time I couldn't really afford a new one, so the shop just hollowed it out and put it back on. Years later when I needed an exhaust gasket leak fixed again, I had a new cat installed. Anyway, during the time I had a hollowed out cat, the car still passed PA emissions without any trouble. I didn't notice any performance differences.
