Forum > Failed Smog Test > Question

1990 Chevy Pick Up C1500 350 failed visual test for headers.

My engine passed the emission portion of the smog test, except the headers I installed do not have an EO#. What can I do now with this problem.
Answer:

Unfortunately, the only thing you can do is either contact the manufacturer of the headers and verify they are not EO approved, and if they are ask them to send you documentation, or your can replace the headers with the approved ones. posted by SmogTips Support
