Those guys are all using aftermarket exhausts which are not street legal, and sold as such. Why do they get away with it? Cops have a hard time catching them; there's a big subculture within motorcyclists of guys having loud pipes, doing stunts, not having license plates on, etc., and then running away when the cops come. Bikes are hard to catch and chasing them often gets banned by the cities because it often leads to bystanders getting injured. They also generally don't have catalytic converters so running those exhaust systems is just a dick move all around. Actually some of the aftermarket exhausts also come with db killers included to reduce sound levels, but those can be removed. So basically it's just back to assholes and lack of enforcement. Some stock bikes are a bit loud, but not that much louder than cars. With the exception of supersports, which only make significant power at 12-16k RPM near the top of the rev range, but even then you have a stock exhaust and won't be running the engine that hard on local streets. Unless you're an asshole.

> Those guys are all using aftermarket exhausts which are not street legal, and sold as such. So find who is selling them, and take away their business. It's what we do to drug dealers. The mechanics will give more of a damn about compliance with the law than their customers do. That won't stop the DIY-ers, but mitigation is five tenths of a solution.

  The problem is that most of the regulations only cover vehicles used on public roadways (at least in the US). Most of these parts will say that they are for "off-road use only", which make it hard to go after the manufacturer or installer. We would need to change the laws to say that the requirements apply to any vehicle manufactured for use on public roadways. Some of the requirements need to be changed from just applying during design/manufacturing to at all times so the majority of the loopholes currently used can be closed.

    What makes it harder is that many of these exhaust systems are used off road only, on dedicated track bikes. You can get a street legal supersport bike for $10-15k new, and with bikes that powerful, changing from a street legal to performance optimized exhaust can make a significant difference. But these supersports are also often used on the streets, just like you see people driving Lamborghinis and Ferraris on the streets (but not often because fast cars are very expensive). Just another thing which makes legislation harder.
