Headers installed 2 weeks ago. Immediately threw code p0420. Added nonfouler to o2 sensor. That code went away and came back with P2096. Added another no fouler to bank 1L1 Was good for 2 days and light just appeared again.
For reference, driver cat had to be pushed way back sitting just behind front passenger seat. I know it's not getting hot enough anymore. Which is why I used nonfouler. I also have a "ringing" sound that flauxuates with the amount of rpms in pipe directly under my feet. Im being told its the difference in sound cause the cat isn't there and the air is now denser so sounds different.
The guy who installed doesn't know what to do tbh.
