are not a factor as they are mounted before these pipes. I have passed Ohio e-check test several times -no problem

Do they do the sniffer test ? Did you have a CEL?
Did they do a visual test?
All 3 tests are done in California and many other States. The bright shiny headers are an instant give away for the Visual unless the headers come with a CARB number. I am not trying to spoil the fun. I love this stuff. But if you get Smog Test problems it will be an expensive mistake.Just check first .Basically if you get a CEL or can see chrome headers underneath you will fail in any State with California Smog Test rules .
