Cool? It's loud as hell and shouldn't be driven on the street. Just like my neighbors built vette only drives to and from the track. It's loud, obnoxious, and far too powerful to be useful on the street.
Many motorcycle riders have gotten this idea that it is okay to speed around at 100mph on the highway when it is "mostly empty" or install loud straight pipes because the cops can't/won't do anything about it. Truth is though, they are considered complete assholes by most motorists for these actions. It may be a generalization, but a larger percentage of motorcyclists are asshole drivers than cars, likely because of a combination of factors; the people often attracted to motorcycles are generally bigger risk takers as well as performance vehicle enthusiasts.
These same motorcyclists will complain about how they were almost hit when a car tried to merge in their lane without realizing that most people don't constantly stare at their mirrors. If you're doing 120mph and pull into someone's blind spot while slowing down, there is a high probability that the driver will have never noticed them.
The same motorcyclists which laugh at Civics and other cars for their "fart can" exhausts go install straight pipes on their annoying motorcycles because for some reason it's "tasteful" when they do it. Just because it rumbles instead of buzz does not make it better. It's still incredibly loud and has no purpose other than to say "look at me."
I shouldn't have attacked you personally on the other hand, I don't know you and I don't know your bike. You pissed me off when you told me to grow a pair
