No I don't think they are very loud, if the alloy muffler has all the gaskets sealing properly and the metal baffle
is in place and not leaking where it's pressed in and not rusted out these mowers are quiet if you're talking about the
old Victa 18, but have seen a lot of people that say they are loud and don't realize they have a muffler problem.
The later 125 and 160 are not loud if the muffler is in good condition.
The Sheerline ad jingle was something like" the hush tone muffler makes the motor sound low"
There are original Victa sales ads on Youtube and the motors aren't loud
