OBD II converters

[Jaymatic]

Now that I have found a shop willing to do aftermarket cat work I am looking into which converter to get. Magnaflow/Carsound has "OBD II Compliant" catalytic converters. What would make a converter OBD II compliant? It's not the cat that makes OBD II cars OBD II, it is the sensor after the cat and the computer, or at least that's what I always thought. So anyway, I can not get an SES light, I would be totally screwed for emissions testing and would be forced to go back to the stock set-up, which would waist a lot of money, and I don't have money to waist. So do I need to get one of these OBD II converters in order to be safe? A lot of people have told me to stay with the stock set-up because I will get a light with an aftermarket cat, but then a few people on here said they haven't gotten a light.

Thanks guys

don't they make like o2 sensors or something to make the ses light go away?

You can get an O2 Sim that plugs into the after cat sensor to make the light go away.

I can't use an o2 sim. If they find out its an o2 sim, I fail. However, the other day I was thinking of something. I know you can use PCM reprogrammers and stuff to help out the computer with compensating for exhaust, intake, rear-end gears and stuff like that. Would you be able to use one of those in order to let the computer know you have a different cat so it knows that the effects of the increased exhaust flow is not a problem, and therefore not causing an SES light? Maybe I should post that as a seperate topic?

HPTuners allows you to turn off the post cat O2 SES entirely.

So yes you would need to swap to a 97 PCM and turn the ses off and just not worry about it.

Shane has a 97 pcm and software/cable for sale for 450 which is a great deal!
