The "CA emissions" A4 models had dual cats, but I was living in CA at the time, and as far as I know they carried the same factory HP rating as all the other 95's. Remember, they added the dual cats, but they probably also altered the PCM tuning.

A 95 with dual cats is to my knowlege the same car as a 96, which was rated at a higher horsepower. I guess the PCM may have been tuned differently, but I doubt it. I think GM most likely didnt bother to list two different ratings for the year, and just stayed with 275 to make it simpler. Horsepower raings from manufacturers are not really all that accurate. Look at he LS1...

So is that why some catbacks will say 93-95 single cat and then also have one thats 95-97 dual cat ?? cuz that has always confused me .... good thing i got the right one.
