How loud is the White Bros E series S bend silencer? Is it too loud to ride in state parks?

 

I know rockymountainatv has that pipe listed for sale but as far as I know White Bros. never manufactured it..........but i also have a pipe on my bike that people tell me was never produced too [img]i/expressions/face-icon-small-happy.gif[/img]

I have no idea how loud the White Bros would be..
