When I lived in Virginia, an old timer mechanic taught me how to defeat emissions testing in areas that had it.
You go to
https://rapidpassvirginia.com/VaPublic/Locations and find where the nearest Rapidpass place is. Dive to that location and build up speed, and then cut the ignition and engine off just before coasting past Rapidpass camera sensors. Do this 3 or 4 times. Since you cut the ignition off and are coasting past the sensors, you will have zero tailpipe emissions when coasting by the imaging equipment. Then you wait a few days and go back to the website to get the Emissions paperwork.
