More than likely the exhaust are made from 321 stainless tubing. The 347 rod is used to weld that alloy with good success. That does not mean another rod wont work but most shops use the 347 rod with 321.

Steve Alderman took me to a local welding fabrication shop in Fort Pierce this afternoon
and they can do the repair. Is there one alloy that's standard for aircraft exhaust systems?
Can one of this group say with certainty what alloy is used in our exhaust systems? It's most important to use the correct welding rod.
