I live in Arkansas, and I've searched the state's official website, especially the DMV section, and can't find anything related to the legalities of removing stock smog equipment. I own an '87 FJ60 and have removed EGR, smog pump, air rail, etc., but I'd feel a lot better knowing one way or the other if this is legal. Based on what I've read and seen, removing all this stuff often makes a truck like mine less of a pulutant than if it's left on. At least that's what I've convinced myself of! Anyway, if any of you guys know the details, please let me know. Or tell me where I can find out. Thanks!
