So I believe you and I are on the same page here. But camell keeps stating that it's the emissions, which I disagree with.

noise is an emission

but from the aspect of "air quality" emissions, i have no idea how an intake would cause your car to blow out more "bad" gasses. now, if you're bypassing your PCV setup with your intake (dumping oily air into the environment) that could affect emissions, but it would not be measurable at the tail pipe with a sniffer.
