Well the law has ALWAYS been the law that no modification to any emissions equipment was allowed. It's not new they are just now choosing to enforce it vigourously. It all started with so many TV shows, yes TV shows showing modifications that were illegal. Some DC bureaucrat saw or caught wind and it has been downhill ever since. They have been going after the manufacturers and sellers since, about 18 months or so vigourously. Some states that will include 67 and up vehicles like here in NV and AZ. They are coming after your cars and they are starting at the source. And the laws are on their side federally. Write your representatives, support SEMA about all a guy can do.
