BillR posted this info on roadfly in connection with some trouble a friend here in Japan has with his japanese spec. E32 750iL with the M70 engine. This might be also interesting for owners of E34 exported from Japan to Australia/Phil's and NZ, the major export markets. Our friend here imported a US spec. cat from a dealer in Arkansas, but this does not have the thread for the special temp. feeler at the end of the cat.
Here copies of BillR's info:
Japan was one of the few markets that required
temp sensor on the back of the cats to warn you when the cats are overheating... this isn't a bmw only thing, i'm pretty sure its all cars in the japan market, I've seen a number of gray market toyotas and nissans with the same temp sensor on them. I suspect if you look at japans equivalent to the epa pollution rules for cars you'll see that theres a requirement for cat temp sensors as a safety device. A badly overheating cat will glow cherry red and ignite any paper or grass etc that its parked over.
Just for your info.
