Guess you need to read more.

If you want to "legitly" pass emissions, get a good catted DP like fabspeed, AA, or CG precision.

Catted versions of Wagner, ER, VRSF, etc, will not pass emissions.

Having said that other people claimed to pass emissions with a catless downpipe (meaning that their catalyst monitor was in ready state) by using an angled O2 spacer on the secondary O2. I forget which thread it was in.

To my knowledge none of the "CEL fix" or other methods (like the VRSF one) ever worked to pass emissions.

Finally, note that some states allow one monitor to not be ready, in which case if everything else is good, you can pass emissions even if your catalyst monitor is not ready to due catless or catted DP that is "not good enough".
