A cheap, safe, and effective way to quiet a noisy portable generator. I don't have a way to edit video, so it's a bit long-winded and unpolished.

Easy to make Genset Enclosure from a - Suncast GS2500 Horizontal Shed Fantech 2SHE1021 10" Shuttered Fan Attic Vents for the intake Exhaust is made from 3" ducting. Have an end cap with a hole cut through just big enough for the small section of tube exiting the muffler and a round magnet inside the cap keeps it firmly attached. Exits out the side of the generator with a 4" dryer vent. I put some fiberglass in between the flexible 3" and 4" vent to stop the outside getting too hot and melting the plastic on the shed. I also added a wireless thermometer to keep an eye on the temperature inside, I have a 120 degree normally closed bi-metal switch I added to this. youtu.be So far the hottest it's got inside was 100 degree's last summer when it was 80 outside. You should double check with the manufacturer to find the max operating temperature of your generator. Sound is reduced quite a bit and its protected from the elements. I made a followup video showing the parts and assembly of the exhaust setup - youtu.be The Attic Vent is - Master Flow 2 in.
