I am interested in what works and improved performance and am not concerned about noise!!
It's idiotic thinking like this, that will be our demise. If you people don't pull your head out of your a$$es, none of us will have places to ride. Remember, you Mensa's, there are more people that don't like dirt bikes, than there are dirt bike riders. Everytime a loud pipe pi$$es off one of them, they are that closer to getting involved to shutting us down. It just baffles me when people think like this.
