I did find a leak where it connects to the giant muffler/resonator so I tightened the collector down and tightened the clamp before the y section as well. Would a leak after the O2 sensors cause this code? I was able to clear the codes with the torque app and cycling the DTC code reader on the dash. I've ordered two new NTK O2 sensors, supposedly they made the OEM ones and work better than Bosch. Anything else I should look for?
I just went thru this. and the NTK o2 sensors are shit!!! They are made in Japan and they just kept throwing a code for me, even after replacing the cats. I had went to get the Mopar. Which are still made by NTK but are made in the USA. ANd I have yet to see a code.
I would just buy 2 cats and have them welded in rather then spending all that money for the Mid section. And the downstream o2 sensors are the one that tell if the cats are bad or not. So I would start there with 2 new downstream o2 sensors. and if u still got code then go replace the cats.
But I just went thru this and that is what happened to me.
