DIY Generator Exhaust Extension Kit
I recently purchased a harbor freight inverter generator for a scheduled power outage that was going to take place overnight. I needed to have reliable backup power to keep my refrigerated goods from spoiling. I chose the Harbor Freight inverter after hearing great reviews on how quiet it operated while delivering all my power needs.
After removing the rear cover and exposing the exhaust system I needed to find a way make a custom flange with flexible tubing that bolted into the preexisting holes and covered the existing exhaust piping while still keeping an airtight seal that would withstand the consistent high temperature heat from the hot passing gasses from the exhaust muffler.

Since my home doesn’t have a backyard and only an attached garage I needed to run my generator with in my garage dwelling overnight without exposing my family to deadly exhaust fumes. This meant I needed find a way to ventilate the exhaust system out of some preexisting vents within my garage.
After removing the rear cover and exposing the exhaust system I needed to find a way make a custom flange with flexible tubing that bolted into the preexisting holes and covered the existing exhaust piping while still keeping an airtight seal that would withstand the consistent high temperature heat from the hot passing gasses from the exhaust muffler.
