I have worked in the exhaust biz for more than 10 years, so I am pretty up on the emissions laws. Emissions requirments are based on the number of "bad air" days a county has in a year. If a county continues to have bad air days year after year, emmisions requirements continue, and sometimes even tighten. In my county, we have only had 2 bad air days in the last twelve years, so as of January 1st of this year, we no longer have any emmisions requirements. No E-tests to get a vehicle registered, no more bogus exhaust violation tickets, nothing.
