Mystery exhaust pipe on MF203

The exhaust pipe that is in between the exhaust manifold and muffler has rotted out. When I called my local MF dealer they told me they have never seen anything like the one on my tractor. I was told that originally the pipe would go straight down and the muffler would be under the tractor. Apparently a former owner must have modified it so the exhaust actually runs along the side and towards the front then exits above the hood. Any idea what tractor the pipe on my tractor may have gone on originally? It does not appear to be fabricated, but possibly from another tractor? The dealer did tell me that when the loader was installed there were other exhaust systems other than under the tractor, but what is on my tractor is a mystery to him. He told me you have to actually look in the loader parts book to look at the other exhaust systems and get part numbers for them.

Any products out there that I could possibly use to fix the rotten section on the pipe? Of course it is on the back side and blowing black smoke all over my tractor.

It is hard to get a good picture because the loader arm is in the way. I did find a picture I took before I put the loader back on which shows the entire exhaust system.

Thanks

Yep, any muffler shop could bend that, Joe.
