I think a dealer would possibly swap a mid-pipe. I had my car tested and there were no issues, my understanding is on cold starts it has higher emissions, but once warm, it is the same as stock. Someone can tell me otherwise.

I am not sure if it would still pass emissions in a state that does a sniff test, but it does not generate any check engine light or affect cat readiness because on the 1M that is only monitored after the primary cats in the downpipes. There is no oxygen sensor after the secondary cats in the mid pipe.
