SideStep

I have been getting these codes ever since I installed the exhaust system listed in my sig. I have done a lot of searching here and other forums. Does ANYONE have a fix for this issue???? Is this code affecting HP???

I have replaced the front O2s with new ones and I have tried putting rear (high wattage) O2s sensors in the front bungs, with the correct wiring adapters to front O2 wiring harness, from LG.... NOTHING WORKS!!!

I am pulling my hair with from this!!!!!!!
