I have DPs and a JB4 will not work to pass inspection if you run catless. You can set the JB4 for auto code clearing, but when you go for inspection it will obviously show up as you cleared your codes. Therefore none of the sensors in your car will have had enough time/miles on them to know if they are running correctly. You will need the DP fix V3 from burger. Trust me, I tried...
Goodluck
