The person who had my blasty b4 me took out the baffle/spark arrestor from the back of the silencer. i know that most spark arrestors are like a little cone made of fine screen but this doesn't have it. with it out there is like a 3 inch hole for my exhaust. if i put it in there is just the little pipe coming out. is there supposted to be a screen in this end cap baffle thing or doesn't it ever have one. i don't wanna go to a atv park that requires one and find out that i am missing something
