Anyone have any ideas where I can get a silencer box 0nly for my xj600 divvy?

I have the Motad nexxus system fitted, the Stainless down pipes are ok, but the silencer has a small hole.

Try here mate,

http://www.motad.co.uk/index.php click on Silencers on the left side bar.

If you don't want to buy a new one I sugest you look in Yellow Pages for a welding specialist and get your silencer repaired.
