MSDS headers + no MILiminators= ?

I think LUCA said her car didn't need MIL eliminators with the header install. Said the car ran perfect and had no CEL.

Also Tourige, he said he checked for codes and nothing came up. There could be soft codes that don't trip the CEL, but can still be detected with a scan tool.

Yeah, many times the pcm doesn't run the catalyst test until certain driving conditions are met. Therefore it may not actually set the light.
I ran without out them for about 6month and didn't get a light until later. I then put in the mil elims
