I get where your idea comes from. These mufflers seem to be the Achilles heal of these tractors. Both my original and replacement mufflers have been welded and reinforced. I seem to think of wanting to add another support to the muffler body, but couldn't find the room. Maybe I did, have to pop the hood!
So I like your idea, does one have to be concerned with backpressure on a diesel like this?
