what about the coating on hookers long tubes? I just ordered coated long tubes 4461-1 i think? Will that burn off at all and screw with new O2s? Never thought of that, didnt think the ceramic coating would burn off. I could see uncoated headers since they may have some oil and schmootz in it from the bending machines. But the coating should be oil free and id asume baked on? I know its gets dipped in a liquid to coat them, but do they bake it on after that or just hang dry em orrrrr?????
