Oh man I keep going back to the twin chamber Harley pipe and laughing so hard that my tummy is hurting :( I don't think I've ever seen a stupider looking vehicle in my entire life. You ride around on that and don't get the shit kicked out of you? Oh wait, right...you're flyin by at 75 mph, or so you say. I'm pretty damn doubtful of that anyways though.
Seriously though, it makes it even more funny that Harley pipes have the twin chambers because they have v-TWINS - therefore two exhaust ports. But as far as I know, your scootard probably has one - amirite?
