did anyone remove the Cat from S2K?did anyone figure out how to bypass the O2 sensor so the engine check light won't come up....thanx...

 

At this time there is no workaround other than to replace the ECU. The ECU requires readings from both 02 sensors. The readings are totally off for the 2nd 02 sensor if you remove the Cat. There are no measurable gains from removing the Cat so why even bother?
