I bent the bottom pipe of the muffler (fits onto the top of the flange pipe) on our M5400 while bushhogging this past weekend. Looking on the Kubota parts site, it seems they've discontinued this particular part (TO1501 Muffler, here's the link to the part M5400 Exhaust). Looking to see if there's a compatible replacement I could use instead. Feel like I lost some of my hearing even wearing earmuffs after it fell off!
