Diversion exhaust

I own a 1999 "T " reg 600 S Diversion. It came with a Motad 4 into 1 exhaust the silencer is scrap & motad are no more.

To keep costs down can i use the pipes with a link pipe to a silencer off a Fazer ect . The pipes go 4 into 2 into the silencer.

Can any body help with a fabricator to make the link pipe ?. The bike has no mot as i am doing it up.

              Made my own rear rack , cut a Craven rack & inserted new tubes to fit it found Krauser K1/2 fittings.
