I don't really want more noise. My neighbors are starting to complain about the noise now. At least the reason why they are so restrictive here in Canada is because they have to be. Any person who works in the woods will be forced out by safety inspectors if they are running modified exhausts in any way shape or form. They do check them as well. Removing spark arrester screens is a very big no no. I'm not worried about safety inspectors with this contraption, but i do worry that the rangers could stop me from riding if i don't have a spark arrester screen.
