Explain this emission thing that states have. I read up on one that in Cali, a B20B is illegal to have in a car. I dont understand why but it is. Here, cops are giving people warning about having aftermarker exhaust on the cars and saying the only thing allowed on a car is stock and nothing more. So what things should I be looking out for if this up coming months when they are looking to have this voted on, or where is a good place to look instead of typing a story, unless you have the time. Right as of now, North Dakota does not have any emissions on vehicals and is great but if it does I think I am gonna be in a bad boat with a B20B in a car. DAM.
