code p0430 system low efficiency, am I losing power?
I installed headers and an off road pipe( no cats, no sims) now I am getting this code, but it doesnt really bother me as long as I am not losing power as a result. What do you guys think? thanks

According to the manual, only two actions are taken by the PCM:
1. The Malfunction Indicator Light (MIL) is illuminated.
2. The PCM records the operating conditions at the time the diagnostic fails.

No you will not lose power but the Check Engine Light will be on all of the time due to you not having any cats. I think Mid America and others have something that you plug into the Heated Oxygen Sensors that are behind the cats that mimic the output of the rearmost HO2 Sensors so that the PCM sees a signal so that the Check Engine Light stays off
