Indian Trail, NC
I was planning on makeing some trips to the forest around here as soon as the trails open, but the person I bought "Blastatron" from removed everything out of the stock silencer. I know I need a spark arrestor to go into the forest blah blah blah, but I don't really know what it is. If I purchased the missing parts for the stock silencer would that be enough?

Why would someone remove that anyways? Do you gain any power from it?
