Code 67
1998 Integra, 4dr auto with B18B1 DOHC engine.
Started getting a"check engine" light a few weeks back, so I pulled the code. It flashed a 67, which my Haynes book tells me is Code P0420, with probable cause "Catalyst system efficiency below threshold". Is this serious? Expensive? Anything a DIY mechanic can handle? TIA for any advice!

Check that first before replacing the catalytic converter.
