The biggest thing that made me go back to stock as much as possible are the SMOG/emission CHP/B.A.R random check points. I've come across 3 of these. They are voluntary to allow them to inspect your vehicle but I still didn't want to even deal with getting caught. What part of Cali do you live? |

Two of the three smogs did include a visual, but I don't think these guys knew what they were looking for. Both times they used a mirror and looked up under the driver side by the door. I imagine they see the cats behind the DPs, and think all is good. You can't really see the cats from under the hood anyway.
Smog is done through the OBD port only, no tailpipe sniffer. I have MMP DPs, and the rest of the exhaust is stock, I'm in the bay area. There is technically a way to use the DP Fix with the JB4, but I had some trouble with that the first time, and I just ditch the JB4 every time I need to smog, and then reinstall. If you are local to me, I'm happy to loan you the DP fix with some collateral, and help you install.
