Pipe vibrating bad

I have a couple of pipe mounts for sale. Thats what it looks like to me. Make sure the bolts are tight up there too...
 
no its none of that. mine did that to. where the silencer bolts to the grab bar in the back. get a chunk of metal with a hole in it and put it between the silencer and grab bar when you bolt it on. if you need further help pm me and ill sen you some pictures of what i did. it really helped alot.
