Xc 500 Lc. Exhaust Needed In Oz

Hi all
First I would like to thank the collective minds for all the great info here , it has been a great help for a newbie husky owner
My issue is that the exhaust pipe on my bike has blown a large whole in the musket end
I would just get it welded up except that it has been bent and repaired before so the metal is cracking.
My next issue is where in the name of two stroke gods when here in OZ can I get this repaired\replacement made.
As with COVID I am unable to get the bike to any one south of the boarded I Nsw and another name I was given Gary Treadwell is proving very hard to contact.
Any info or if some has pipe they handed in back shed they wish to sell etc
I would be most greatly
Thnx in advance
Wacko Ocker

Noel from Pipework techniques did an excellent job on my 500cr pipe a few years ago. Great bloke.
