how to set it up so it won't throw check engine sign? do I need additional stuff to fool the o2 sensor?

JB4 will supress cat codes, need dp fix to pass inspection.

Catless DPs trigger CEL, JB4 set to auto-clear codes will remove that but you won't pass emissions and it makes it harder to troubleshoot since ANY code is auto-cleared. Use the BMS $80 dpfix solution, turn off JB4 auto-clear of codes, win.

awesome now I get it, so where does the DP fix hooks up to? and the factory 02 sensor is disconnected??
