8.2 merc 2nd 02 sensor bypass?

[Jonas Grumby]

Does someone make a ez plug for the 2nd 02 sensor bypass on the cat to fool the computer when changing out exhaust on the 8.2? I see CP Performance has a $700 box. There are some articles about a spark plug spacer used. Most of the after market exhaust for the 8.2 have a bung for the 1st 02 sensor, you need it for afr. But nothing for the 2nd due to the cat would be removed.
I don’t need any Karen’s telling me about smog, or smog laws.

Like I said, after market exhaust(headers/imco’ s) don’t provision for the 2nd 02 sensor.

then I think you are stuck with the $700 box or an ecm reflash
