I have 1600 hours on my Dingo which I've had since 2012. Mostly a fantastic machine. However, my maintenance records show the muffler has been replaced five times. This last time in less than a year. Toro replaced it under warranty. The muffler itself is fine. The issue is the steel corrugated looking flex bellows pipe between the Kohler gas engine and the muffler. first question is what causes this to break? The engine has just been replaced, not bad motor mounts. Idle is 1275-1320. Maybe it's just bad quality. The muffler flex pipe breaking is a known Toro problem. I would like to get a cheap better fix as the mufflers are going up over $400 now. The two pipes are 1.5" dia on each side of the bellows. I tried to insert a piece of Surebilt flexible galvanize steel exhaust pipe with hose clamps and exhaust sealant. Wasn't going to work well. Would prefer to find steel flex bellows for 1.5" dia pipe and get someone to weld it in. The fancy stainless steel Car flex pipes don't look good either. Any ideas?
