CEL Code 67 Anyone know how to fix

Man just when I thought I just had the problem fixed (ie. busted distributor) I get another problem. I got a CEL code 67: Catalyst system Efficiency Below Threshold malfunctioning or defective catalyst system.

Anyone know what this is & how to fix it? Its a 99 civic si with 116000 km on it.
