First time at a site that requires generator exhaust be vented over the roof, name brand kits are in the hundreds so I ran to the store and grabbed $7 in aluminum gutter and a hose clamp. Working like a champ, figured I'd share in case anyone else found themselves in the situation.
Let the haters hate! Pretty ingenious! Looks like you’re allowing some air flow at the bottom entry. But I would find a way to connect it and leave more of an air gap around the exhaust pipe going into the gutter. Would not worry about the bungee cords as the exhaust is probably cooled down enough at that distance. Get a CO monitor not just for your rig but all the other rigs around you.
Like this idea but have a question.
Doesn’t there need to be a gap between the exhaust pipe and vent pipe, to ensure a draft is created and the gases flow out properly?
That’s what I always see on the commercial kits.
For even cheaper generator exhaust remember to fill up in the morning when the temps are cooler and the fuel is more dense.

The more you know!
Nicely done op. I’d have done the same.
That’s hilarious
If you run into issues or to ease the concerns of others. I think there’s solar powered vent caps that have little fans you could put on top to pull the exhaust up
Make sure you and your neighbors each have two working CO monitors with this setup.
