Oxygen Sensor Simulators

[moparmania]

Anyone try any brand o2 simulators for the rear o2 bungs when you install headers with high flow or no Cats ?
this one is new . Has the right square connector The rear 02s are a useless sensor just monitor cat condition . No effect on running .Just like to knock off the light so you can tell if anything else ever comes up . This one is by Casper . Anyone try it yet ? The truck guys say it works great on their Hemis.

Wondering if anyone has tried these?

Thanks,

I wonder if they'll work. The system pushes the Cats to see where they respond, then back off when it's satisfied. That "sensor" would never change, I expect.. So it might throw a code.
