Do you know where I can get one?

Both sensors are new and code P0422 started immediately after new cat was installed. I guess it could be a coincident?

Has any of you seen a, I call it a "bung adapter"? It screws over top of the O2 sensor and has a very small opening. Then the whole thing screws in the original bung. I have only seen one of these adapters once before and it was on a street leagal Audi TT/Rally car. If anyone knows what I'm talking about, might you know where I can get one and if you think this would solve my problem?

If it is due to a cold cat then the cel should come up just after start-up. The P0422 code usually comes on after a highway cruise. I don't understand why this is happening, but I will give IPD a call in the morning. Thanks

It is not a Magnaflow. I is a Race Cat used on Rally cars. I am positive on brand but can find out. My freind biulds rally cars in Aylmer Quebec and He put my exhaust on for me. Cat was brand new when installed.

Since I installed my Hi-Flow cat I have a reaccurring P0422 CEL? I know it is related to the rr 02, and it is brand new installed @ same time as cat. Correct me if I am wrong, but it is triggered due to higher amount of CO2 of exhaust gasses. Is there a way to fool the censor? Or I could heading in the wrong direction? Please shed some light.
