mi3nboijosh Posted October 17, 2012 Share #1 Posted October 17, 2012 I live in California and failed the visual inspection part of the smog because the technician couldn't find the C.A.R.B. oe number for my headers. Did they even have CARB numbers back in the 70s? (1976 280z). Link to comment Share on other sites More sharing options...
mi3nboijosh Posted October 17, 2012 Author Share #2 Posted October 17, 2012 Mine headers are stock but he still asked me for it. That's what I'm asking. Link to comment Share on other sites More sharing options...
Arne Posted October 17, 2012 Share #3 Posted October 17, 2012 Nissan didn't use tube "headers" on these cars, they all came with cast iron manifolds. Link to comment Share on other sites More sharing options...
mi3nboijosh Posted October 17, 2012 Author Share #4 Posted October 17, 2012 I'm still puzzled about why he said I needed the EO number to pass when everything is stock... Link to comment Share on other sites More sharing options...
John Coffey Posted October 17, 2012 Share #5 Posted October 17, 2012 The tubular header is not stock. There have never been any smog legal headers made for the Datsun S30. The market is too small to go through the expense of getting a EO sticker. You will ahve to remove the header and replace it with the stock exhaust manifold to pass smog.
