P0420

97 lt1 m6
i am stuck here, i replaced the o2 sensor and the problem didnt go away, nothing rattling in the cat, no funny smells or anything that would indicate a bad cat, short of getting it tuned and the rear o2's tuned out, whats left to check?

and just to confirm p0420 is for the driver side correct?
