Smile Cat converter and P0420 code

There has been multiple posts in regards to above codes. i thought i will share this info with all you folks.

i have a 2000S 4.0L, after reading several posts here i tried LUCAS oil never helped to get rid of my CEL light every 50 or so miles it will pop up.Car was running good, no loss of power and fuel trim were good.

After researching for California legal, cat converters( hard to find), went to my local muffler place and he replaced it for 300/- labour and parts this one is legal for sale in CA. company by the name CAR-TEX, compared to original one 1000 and labor.

No CEL light, checked o2 sensor curves they are good

i forgot to include, on inspection of the removed cat, fwd part of the matrix was completely melted. It justified for the removal.
