You need the fresh air space, you know like a double wall stove pipe.
The way Jack has his are just like the ones they sell at rv places.

I would still use a 3" or 4" PVC conduit for air space.  I am going to make miine basically like Jack's.  I am heading off to buy the 90 for my exhaust right now.

Jack, since your stack just hangs from the gutter, how do you keep it from slipping off if someone bumps, or is that not an issue?

That has not been a problem so far.  The vertical stack sweep is a snug fit on the muffler outlet.  Jack

To kill a dead horse, as the saying doesn't go,  garage exhaust hose works well, is easy to locate where you want it, is easy to store, and does not get as hot as metal (it does get hot though).  If one does not like the color, there is a rainbow at a paint store.

I built one with what I had laying around. EMT compression coupler into a 90 degree EMT bend. The vertical stack was double wall gas pipe that can store easily in the bay. It is easy up/down/storage, and the materials are inexpensive. We use the hose where I work, but it is not cheep and requires an exhaust fan.


Here is an older post where it was covered:

I ended up buying a custom piece of exhaust pipe and a 10 foot 3" PVC pipe to try making a generator exhaust stack.  Total cost was about $30 versus $90 or so for the Genturi.

The Camping World version is $150 now.  The cheapest I have found the Gen-turi for is $130 plus shipping.

My version is $30.  If it doesn't work and melts I buy a different type of pipe for another $10.  I'm almost certain it won't the generator as I am using the same principle as the Gen-Turi.

The one I made has lasted 8 years so far and it still working great.  Since I had mosr of the parts laying around in my shop, i doubt if I have more than $10.00 invested.  As with yours, mine also uses the same principal as the $100 one.  Jack
