Careful about that: Exhaust is hot, and it contains a pretty good amount of water. Neither one of which is desirable for inflating something made of plastic.

Anecdote: I have heard stories of someone in my car club who used the exhaust from his car to inflate a balloon (used to hold a sign aloft). It started out OK, but after a while the water in the exhaust started condensing out and overloaded the balloon. I don't remember if the water went back down the exhaust pipe and plugged up the motor, or if it just leaked out of the balloon, but either way it didn't work so well.
