Cat-Back Exhaust..(PLEASE RESPOND)
Wednesday, May 11, 2011 6:47 PM
I put on Megan Racing Cat-Back Exhaust and took out the silencer after I drove it a week. Soon after that the Check Engine Light came on. After scanning it, the results were that there was low voltage on the O2 sensor, Bank 1, Sensor 2. I put the silencer back in and reset the computer but the check engine light came back on. I now know for sure that the sensor is bad because I already checked the wires coming and going to the manifold and cat. I was just wondering if anyone else has had this problem after putting on aftermarket exhaust. I know with the O2 sensor being bad it can potentially ruin the Catalytic Converter which would be a nightmare. Please respond with your input. Thanks!!
