workin on my 97 twin and found all this in my stock can , and there is more in the pipe i cant get out. im assuming its a baffle from inside the pipe , is there any problem running this pipe once i get the pieces out.
had the same type crap falling out of mine last couple of years everytime i take the silencer off. so far, no issues and my daughter is not at all easy on this machine. i just shake it and let the stuff fall out, let her ride it for awhile and shake it some more. probably should find a replacement, but not too concerned at this point.
