Code 1153 With Long Tubes
 

Im not sure if this is the right place for this but Ill start here anyways.
I installed LT headers last year W/O cats. I put the factory O2 sensors back in and after about 50 miles code 1153 poped up (insufficient switching). Cleared it with my predator.
This year I replaced the sensors with new Bosch ones same thing happens after about 50 miles, code 1153 again.
Ive heard that this is common when LT headers are installed W/O cats.
Is there anything that can be done short of deleting the sensors?
Anyone else take care of this problem?
What would be the fallout if I delete the sensors in the PCM?

Thanks in advance

the rear ones need to be simulators, I think it's a temperature issue

Yep, if possible get your PCM reprogramed and delete all the emission crap.

Yep the rear ones are sims and the front ones are new snesors.
