Don't make more out of this than is likely there. New standards were set, some companies chose to deliberately ignore them. Effectively waving a red flag in front of the bull. In order to keep all the others in line, a hammer blow to those ignoring the law had to be made.
This is just like back in the 60's and the 70's both, when new vehicle standards were enacted. Most folk in business complied, some were foolish and refused. A few hammer blows were applied, and you now have clear labeling about what is not legal on the roads, as well what is not legal in California.
There's a darn good chance in fact that other businesses were pushing for the hammer blow on the scoff-laws. They don't like it when they abide by the laws and regulations, while others ignore them and get away with it.
This is yet another reason to save your stock headpipe and mufflers, or run S/E mufflers with the stamp. The day is coming that you'll need those items to either pass inspection or re-register your bike.
A bike without a cat, puts out lots of pollution. Your average 5 hp lawn mower, without a cat, puts out more pollution then any car built from about 1996 to present.
As far as noise goes, there is no need for open pipes on a street bike.
A bike, or any modern day vehicle for that matter, without a catalytic converter, that is in "proper tune" emits no more pollutants than the same vehicle with a catalytic converter ... The problem comes in when the vehicle is "altered" in some way or a component in the system fails to operate correctly ... That's when the catalytic converter acts as a "furnace" to burn excessive particulates that haven't been "consumed" in the combustion chamber.

Utter and complete bull crap!!!!!!!
Cats can reduce the emissions by about 99% when all warmed up.
Until about 2 months ago, Maricopa County AZ (Phoenix) was the only place in the country that had mandatory motorcycle emissions testing. The program was discontinued because motorcycles are not a big enough source of pollution to make the program worthwhile.
We have some nasty air here in Phoenix, but a lot of it is due to the dust particulates - it is a desert, after all. The folks in Washington can't figure that out, though.
The numbers just don't add up. Motorcycles make up barely 3% of registered motor vehicles in the US. Add the fact that the average yearly mileage for motorcycles is 6,000 miles compared to an average of 18,000 miles for passenger vehicles. We haven't even gotten into commercial trucking, buses and so forth.
Even if a motorcycle emits 25 times more pollutants than a car the total amount of emissions actually contributed by motorcycles for an average year would be so infinitesimal to the point of being impossible to even quantify. Its ridiculous.
And now the EPA wants your lawn mower! What's the average run time on that a year, a single cylinder for an hour a week? Half the year in some climates. Really!!
The EPA is just another govt agency gone wrong.
Total number of vehicles[edit source | editbeta] According to the US Bureau of Transportation Statistics for 2009 there are 254,212,610 registered passenger vehicles. Of these, 193,979,654 were classified as "Light duty vehicle, short wheel base, while another 40,488,025 were listed as "Light duty vehicle, long wheel base." Yet another 8,356,097 were classified as vehicles with 2 axles and 6 tires and 2,617,118 were classified as "Truck, combination." There were approximately 7,929,724 motorcycles in the US in 2009.[5]
Livestock are responsible for 18 per cent of the greenhouse gases that cause global warming, more than cars, planes and all other forms of transport put together.
