I may need new catalytic converters for my [April] 1992 348 Speciale tb. Does anyone know where I can find a reasonably priced aftermarket set? How much would they cost at the Ferrari dealer? I know some have seen fit to remove completely their catalytic converters, but I am not inclined to do so as I am not a mechanic and I do not understand all the details regarding such a move. The 348 "Check Engine" light-Bad CATS-bad Exhaust ECU-bad O2 sensors-etc. problems are absolutely confusing to me. They constitute a never-ending MAZE that I don't think I'll ever understand.
