Exhaust pipe repair?

[Carl Hill]

I have a pipe for a (75?) 250 with a damaged muffler. Would like to get it fixed to run on my hare-scrambler that I run in vintage MX. Anyone know a place that can repair it? I would be ok with having stock muffler section cut off and a "stinger" welded on so I could attach an aftermarket silencer. Any suggestions? I have an aftermarket (hi point?) pipe on it currently. Great top end but it seems to have lost a lot off the bottom.
