http://www.uncrate.com/men/gear/auto-addons/titan-exhaust-air-jack/. I would be worried though that putting that much back pressure on your exhaust system could be damaging...somehow? Anyone with working knowledge want to weigh-in on that? I'm not considering it, just curious about the physics of it all...

There won't be any back pressure until the bag is full.
...agreed, at which point it will begin to lift the car. That's what I was gettting at.
This design is not even SAFE! It could roll like a ball. They should have gone with something more rectilinear.
I would not get under a car jacked up with that if you paid me.
If you look at their website it looks like the new ones are a cylinder (not the ball) and it looks like you get a little blue compressor to fill it up... Which makes me wonder why do you even need the exhaust hook-up in the first place?

I'd never get under a car with that.
What if it snags on a sharp piece of underbody while you're in there? 5 seconds to GTFO... yeah, right.
The factory jack might not be the most robust, but at least it doesn't roll and is made of steel.
it may be novel, but it is not new - I saw an idea like that around the time the 914 was introduced to the world. I think it's even on the same page in a 1969 issue of Popular Science...
I believe the Paris-Dakar racers have used that type of jack for years. It's one of the few types that will work when wheels are so deep in the sand that the doors sills are touching.

You could call it the "virginity jack". Because one prick, and it's gone...
