I have a MT52 that I have welded up the broken exhaust several times. Wondering if others have the problem or fix? The Motor mounts are fine, bolts are tight. 2nd mount is tight. Machine does not vibrate excessively. I bought a new muffler from bobcat that was back ordered for 3 weeks. ( I would imagine others are having this issue). The new exhaust broke with in 1 hour. I was thinking about two options. Floating rubber/steel joints in the header area & 2nd mounting bracket in rubber. or Soild mount by bracing off the 2 head bolts to the 2nd mount and create 1 solid system that moves with the motor. Anybody out there with the same problems?
