    O2 Sensor Simulator?

    Has anyone here installed a High Flow cat or full Cat Back exhaust and had the engine light come on? I did this a while back and it keeps comming back on. some error code saying the engines catalyst system is not running at optimum efficiency. When I reset the ECU The car feels like it has a lot more power until the engine light comes on again. From my research I hear you need to buy a O2 sensor simulator. Has anyone else used these? If so I would like to know what brand and where to buy one to make my engine think all is good again :)
