Well, i finished up a lot of stuff today, specifically my 3" exhaust and downpipe. the only thing I'm missing is my option for a cat. I heard that we can run catless just fine if i only had one oxygen sensor, well.. i have two. I don't want a cat so i'll get that out of the way. i live in florida and we don't have emissions. I have my 2000 for daily driving and the 99 is for "fun". is it going to be possible to run catless without a cel? if so, how? i know it's nothing like our mustangs where i can just turn the rear o2's off, so if anyone has any info let me know. :D

I think your other option besides turning the checks off in a tune would be to use some sort of resistor on the sensor plug. You'll have to do a bit of research but I believe you should be able to just solder a specific resistor between two points on the connector and you'll be good to go.

Go on, do just a little for the planet, keep the cat ;)
