not really answering your question, but the Volvo 340 had no cat in 1989 (the year unleaded petrol first became widely available) but IIRC it was a pioneer in its last years in the UK, as it had one in 1991 and probably 1990. The 216 was available at that time but IIRC in 1989 cats were so exotic (VW?) car adverts showed owners calling to the cats "Here kitty kitty kitty!"Whe did they start to put catalytic converters in 216s? i thought it might have ben when the facelift came with the grill and indicators?
