So I'm trying to pass my 91 318is with an s50 to pass the BAR test but I keep failing emissions. First time I took it, I warmed it for about an hour and when I got to the referee I kept it on. I was on stock e36 cats and resonator. First time I failed. 2 months later after I switched the plugs, oil filter I took it again to the referee and I failed again. So I thought I would change the cats. So I got new cats (Walker 80801, Suppose to be direcct fit for the 95 e36 M3), and a month later I took it again. Warmed it up the same way I did the first time. Not only did I failed the smog, referee said I got the wrong cats:hitler:. I was pissed. He saying that the cats are the wrong ones and that this year only uses one cat not two?? I didn't really pay attention after the test failed, but he said he called BMW and that they told him that the e36 M3 comes with 4 cats. His his book says that the cats I bought are for one cat cars or something like that. He said I also probably failed because of the cats being the wrong ones.
My question is for people that are BAR'd and have aftermarket cats, what cats did you use?
