Ha, they can be tuned to pass, but in the state of Utah it is illegal to remove any factory emissions equipment unless it no longer works, in which case it must be replaced with more emissions crap that works. If a mechanic looks at your engine and sees all the factory hoses gone you're not going to pass.
I have a Weber and Pacesetter on my truck. I live in Layton. I got around emissions by getting a P.O. Box in Toole and registering there. No emissions in Toole yet.
