Thanks everyone for the replies. Charles S, I have a Champion generator with the exact same muffler that is way louder. After listening to both of them run for several weekends, it’s the engine itself that is so quiet on the HF Predator generator. I would buy one tomorrow but the HF is not a 3200 watt unit, it’s 2 1600 watt units that can’t be combined. SAS 289, my 196 has a 3/4 crank, my reason for considering a replacement was vibration. My oldest daughter (43) has a non hemi Predator on her Baja Viper and it runs much smoother. OLE4 I’m not planning to do any mods to the engine. The only thing that I did to the 196 is back out the governor screw until it would go 4300 rpm when I had the stock clutch set up. Now that I have a torque converter about 38-3900 is all it will do and the top speed is 42 mph. If I bought a new HF 212 I think I would try the hemi. Jay
