Just wondering how everyone else dealt with this problem. I have a smog legal header from LC with the carb# and all legal like. I was told I still have to have the pre- heater hose attached to my air cleaner to pass. I saw the contraption that downey sells to attach it to a header and I made my own. I am just curious what anybody else knows about this, been told, ideas, I am hoping that he will accept it. Thursday is dooms day at the local test only shop.
