    There's definitely a major cost saving to the factory from omitting the catalytic converter on bikes destined for markets that don't have strict (Euro3) emissions standards.

    How do I know this? Someone stole the converter out from under my Toyota 4Runner in California, and it turns out there's a whole ecosystem of catalytic converter shops to replace the tens of thousands that are stolen each year. In an earlier post, ZMC888 noted that that a converter contains platinum and rhodium to convert carbon monoxide to carbon dioxide. Don't know how much rhodium costs but did you say platinum? That sells for $1400 an ounce. Crackheads, tweakers and other low-lifes prowl through neighborhoods crawling under cars and trucks -- sometimes even carrying battery-powered angle grinders -- nicking converters and taking them to the Oakland waterfront where they can sell them for $20 or $30 to guys who probably send them to China to extract the platinum.

    I drove my now-extremely-loud 4Runner to a place called The Cat House in San Rafael and had to shell out $400 for a new converter. The guy was doing scores of these a day -- all of them post-theft replacements. A whole business driven by theft! I have to say, the thought did occur to me that the thieves could save a lot of trouble -- and perhaps do -- by selling the stolen converters directly to this guy. Anyway, I insisted the guy weld my presumably "new" converter in place, rather than just bolting it in for the next tweaker to unbolt. And I demanded one of their Cat House t-shirts.
