I use an electric heater in my room, and every time I turn it on, or any electric heater for that matter I get really sick at my stomach and a headache and it's real bad too like reach for the trash can kind of bad. I just feel weird over all. and I almost know it's the heater because I've turned it off and the symptoms disappeared almost immediately (It also got cold really fast too) and I turned it back on same thing. I've tried this with several heaters. but I really have to have something because the outside temp is below zero I believe and this is an old house with poor insulation.and I know I don't have Carbon Monoxide poisoning because I DO have a Gas stove in my bathroom (The old kind too) that I leave burning constantly, but I can sit around that thing all day and not feel any different unless I shut the door for a shower then I might get a little light headed but that only happened to me once and I was in there for a LONG time. plus we have a brand new Carbon Monoxide detector right by it.
You've answered your question already. The only reason for speed bumps is to keep drivers at or below the speed limit for that area. Usually to protect children and pedestrians.

You could actually go down to 8 inch flex. Which would far better suit you. You need the 8 flex, a bag of zip ties to connect the flex. If the supply vents are in the floor and are the old grate style. You can take a piece of sheet metal cut an 8 hole, then insert a start collar, and an 8 Elbow. That way your not having to redo the supply feeds. Basically it would be a T and the center of the T would have the start collar in the center of the pan with 1 lips so you can zip some screws in there to secure it. And yes you will bet getter air flow and you wont loose the heat transfer like you did with the old cannon pipes.
Yes the airflow will be much better my friend
