Ok, so I'm a little curious about the Two Bros racing exhaust. Before I begin I would like to state that I've already installed it on my '09 FZ6R and love it, these are simply questions I'm curious about. First off, I live in Montana where there is yet to be emission regulations, on motorcycles at least. Does anyone know with certainty what states do have strict emission regulations on motorcycles, i.e. they must be tested before registration? My second question is, has anyone with the Two Bros exhaust tested the emissions? I'm curious to see how bad it really is compared to the stock exhaust (which sucks). I know this isn't by any means an accurate representation of emissions, but after about 500 miles put on that exhaust, I ran my finger along the inside of the pipe and it was totally clean. Unfortunately no one in my area has emission testing equipment that I know of, so I was hoping someone from a more regulated state might have had my same curiosity and tested it.
