Just got my 2019 M2C and it has vrsf down pipes. I need to have my emissions testing done and my state (MO) allows for 1 "not ready"monitor. Not sure about these "not avail". MHD 0 tune M2cs. Any thoughts? (See pic)

You have aftermarket downpipes but unsure if you will pass smog? If they are catless you will not pass. If they are catted then yes, you should pass. Tune or no tune your CO2 emissions will be off chart. |

Yeah, had to have a spacer placed in to get the o2 sensor away from the flow. Cleared codes, made sure “stock down pipe” was selected in MHD so it didn’t auto clear codes and drove the car for a couple days and tested again.
