I’m replacing my blown out muffler on # 639 with a walker 22771.  The muffler is much smaller (and lighter).  I notice the stock muffler is rigid mounted to the coach frame.  I been around a lot of cars, boats, airplanes, power sports, etc and cannot recall ever seeing any part of an exhaust system rigid mounted to the frame of the vehicle. Is there some valid reason for this?  Is it just a compromise Newell chose due to the weight?  My intention is to mount  the muffler from flexible exhaust hangers, but just want to throw it out to the gurus in case I’m missing something.
