Does anyone know what the secondary O2 sensor controls on a 2006 LC 100? (1 Viewer)

I'd like to fabricate a set of custom mid pipes to replace the cats on my 100. The secondary O2 sensors, I think only made on 2006 and newer models, are screwed directly into the cats. I wanted to find out if there is A way to bypass them or simply screw them into the mid pipes without throwing a code.
