Your mechanic is wrong. The "probably need a new cat. code" is
"P0420 - Catalyst Below Efficiency Threshold." Having dealt with a bad catalytic converter, I suggest not wasting time with an aftermarket catalytic converter. Midas couldn't put one on that would last for more than a couple of months without triggering the P0420 code, so I bought a used OEM unit from someone here who had done an engine swap.
