I have a 3400 watt duel fuel Champion RV Generator.
I want to quiet it down. Are there any fixes that won't alter the generator by cutting, welding, drilling, pounding, sawing(you get the picture).
I have heard of fastening a 1 inch diameter "L" tube about an inch from the exhaust opening, reaching about 24 to 36 inches above the generator will make the exhaust sound go up and disaate higher in the air reducing the noise.
Anyone hear about this and if it really works.
