rear 02 sensor question

[RoadconeTuning]

do the have to be installed in the pipe if MILS are being used.

I can't say for sure but I remember reading something somewhere that the EEC still check for the sensors to be there. The MILs only alter the signal coming back to the EEC so the EEC reads it as "Everything is A-ok!". I supposed you can leave them out of the midpipe but electrically connected. But then you'd have to plug up the hole.

They have to be in the pipes. You will get an o2 circuit failure code if they aren't.
