One thing I forgot to mention: the shop where I used to work was able to fix several P0420 cat efficiency codes by performing a BG induction service. We basically suggested that as a possible fix, rather than converter replacement, and several times, the chemicals in the cleaners actually restored the converter to working order.
Had a V6 LR3 with cat codes well over 100k that we would do an induction service and use bg 44k every time he filled and it took longer and longer for the light to come back on so we knew it was working to clean the cats a bit slower then usual but still cleaned them.

Go get your codes read and get back to us with your current fault code numbers, not your old code numbers. Are your cats noisey, do they rattle, what octane gas are you using and had you ever lost your head gaskets.

The shop I used to work at replaced about a two dozen converters on various OBD2 vehicles in the 4 years I worked there. From what we found (and from before I worked there): universal cats will usually trigger a P0420 code within a 6 months. Aftermarket cats same code within a year. Oem cats no code for 5+ years. Used OEM cats same lack of P0420 code for 5+ years. The best place for used converters is Brown Recycling Mfg., Inc.. I have never checked on a Disco cat, so I don't know their stock. Some of the recyclers on this board would be worth a try also.
Just my 2 cents.

i did the diagnostic test and all the sensors read fine. exception cat converter, no codes just N/A. so i plan to take it to a muffler shop to see what is the issue. i have no rotten egg smell and the gas mileage is good.
