Or-E-gun has always sucked because it's fixed year, and not based on a specific age. So everything after '74 (IIRC) is required to hit DEQ. That being said, I have built cheater circuits for O2's (nothing more than a resistor bridge) to pass emissions. My old Focus was running Vortex S/C, full length headers and no cat, and yet passed emissions every time. Just glad they didn't pop the hood, or they may have tried to do a visual!
