    Mark please update after your cat procedure. I'm due for CA smog real soon. The last smog I was told cats were bad. I'm @ 139k miles. Want to weigh options as to your choice vs. direct fit from some of the sites given earlier. I know OEM style will cost more. Anyone done the OEM style direct fit?

    Thanks all

    Since I wanted stainless steel and the cat had to be "Californicated", I went with Magnaflow and will have the muffler shop weld them in.

    Re: or

    I have the Magnaflow mufflers and no problems with them. I would think that the cats will be good as well.

    Other than oem the only other converter I

    heard of with BMW mentioned in the same sentence are DEC catalytic converters. They are rumored to work well. I think they are around 350.00 each, I priced them a while ago for my 840. On a side note I took my car in for a smog test in New Jersey today. They got rid of all safety inspections just smog now. Great! Junkers galore coming to a theater near you! I was nervous I was going to fail with a nikasil block and 185k on the motor. My co was close to the limit 2 years ago. I passed! They don't even give you the results anymore! Would of liked to have seen them. Anyway I'm sure you know that the oem ones are expensive. Good luck!

    Catalyst time

    Son brings the hand-me-down 92 850 back from school last weekend saying it won't pass smog. Sure enough, catalyst failed on the left side due to a long-term vacuum leak (high CO at idle with CE light out). Anybody know a decent, yet cheaper OE replacement? Better yet, anybody have a donor catalyst out of a parts car they're willing to sell?
