I've got a 97 Z with dual cats, but in my mind, I can see this setup on my car:

MAC mid-length headers for 94-95 cars with single cat leading to Hooker catback exhaust. I would use O2 simms for the side where a cat would be missing.

Is this possible, or do I NEED to have both cats. I will have to pass Dallas emissions, so I can't go ORY (unless you know of a hookup--PM me! ) Trying to go cheap as possible, that's why I'm cutting out the other cat.

Thanks!

With O2 sims you dont need any cats because their fucntion is tell the PCM that the cats are working fine.

You might not pass with just one cat. JMHO

Really?? I figured that since 94-95 cars would pass with one, wo would the 97 and an O2 simm. is it in the same location as a sotck 94-95? I thought it would be because of location under the car. hmmm....

If they just scan the PCM he can with O2 sims, it'll pass with 94-95 style smog hook ups and a cat.
