Check engine light? O2 Sensor?
The check engine light came on today. I put a 3 inch turbo back exhaust on my car with no cat. The car was fine for days and after driving the car hard for a little bit the light came one. The code was for cat deficiency. I cleared the code and its off now but what can i do so it doesnt come back on?
