I just took my mufflers off to polish them and even though they look new on the outside one of them has some loose material inside. When I turn it over I can hear the material. It sounds correct when running and does not seem to be any different than the other side. It does not seem like there is much loose material inside but I read on another list that back pressure is important and even though I don't think they need replacing I wanted to see what others on the list thought. I do not want to burn a piston because of this.

Thanks!!!
