Need some help. Installed Hooker Comp Ceramic LT Headers and am running no cats & no rear O2 sensors. I was told by a local exhaust shop that the O2 Simulators do not always work. I have a Superchips Microtuner. I want the car to run right and have the engine light turned off. Installed K&N Filter, SLP Airbox, SLP MAF & bellow. Any & all help is much appreciated!!!!!

Having a CEL from the rear O2 sensors missing won't cause your car to run bad...but there should be an option on the Superchips tuner to turn it off..

O2 simulators are now illegal, the only place you may find them is e-bay.

A tuner should be able to "turn off" the rear O2's.

I had no problem finding O2 simulators for sale....

We have O2 sims as well. For off-road use only. The ones we sell have the built in diagnostic circuit. Lots of the ebay ones fail and you have no idea.
