You can get them on Ebay like i did or direct from Delkevic & yes i fitted it myself very easy to do 
great thanks. How easy is easy to do? Im certainly no expert unfortunately!
It is quite simple,there are only 2 bolts to undo.
1st undo the clamp where it joins the down pipes,
2nd the bolt on the footrest/exhaust hanger & pull it backwards,
when you take off the old can you need to take off the nut which is held in by a tab just bend that enough for the nut to come out.
There should be fitting instructions with your new exhaust,but if not when you assemble it, put gasket in the link pipe,then slide it to where it joins the downpipe,don't forget to put the small clamp on too,(try to do it on the sidestand so you can line up the mainstand with the stop),
then put the strap around the silencer,push the can on the link pipe,line up the strap where it bolts to the footrest but make sure it is on the outside not the inside of the hanger like the suggest!!
When your happy its all lined up tighten it all up.
(((((WHAT I WILL SAY IS, WHEN YOU ORDER IT,MAKE SURE YOU ASK FOR THE b SHAPED EXHAUST STRAP)))))
Good Luck
