Will have a scan around and see if I still have mine but Lester is correct in that the instructions are not exhaustive ( sorry
) Basically the pipes are numbered and there was a diagram to show which pipe goes where in the header ( but they only fit one way ) The silencer mounting is just a couple of captive nuts / bolts.
I found the system quite fiddly to fit when getting the pipes into the header far enough to clamp. I tried fitting one pipe at a time but that seemed to push everything out of line so the final pipe wouldn't fit.
Finally I would advise against using the supplied 'trumpets' as they are very tight when trying to get them round the tight bend in the pipes nearest the head and can scratch the finish. Either use standard split shells like I did or you could fully ( or half ) split the supplied ones I guess.
If you have no luck can take a piccy or two of my system if it helps
