Why can't I find 02 sensor sims for a 97 GT???

I remember hearing something about the manufacturers being pressured by the EPA for selling them. You can always make your own though:

They don't make them anymore. EPA bs. You can either make some like stanggt1995 shows or you can turn the rear ones off in the tune. My rears are turned off in the tune and I still pass smog in the Nazi state of California.
