I have a 2010 SS Camaro with bbk shorty headers. I took it to get smogged today and the smog guy asked was my headers California carb compliant I said yes because when I purchased it them from Summit racing in the description they said California carb compliant and gave E0 number if they wasn't California car compliant they would have never sent them! When it came time for him to smog my car and he popped my hood and checked my headers for a EO stamp but didn't find one I gave him the EO number from the header description he said he had to see his stamped on the headers. Does anyone know where the EO stamp would be located on California carb compliant Bbk
​​​headers?
