Fitting another model muffler to ’00-’02 Magnum?

So I need to replace my muffler, want something factory.

The ’00-’02 Magnum muffler have the unique 12:00 and 6:00 mounts.

Everything on eBay is $80+ and up.

Wondering if anyone has tried retrofitting say, a Sportsman muffler from another year or model, plenty of those on eBay that are way cheaper.
