If you introduced an induction device (a scoop, if you will) on the exhaust system, say beyond the cats? It would draw in air at high speed, creating a vacuum and would draw the exhaust faster than the exhaust would normally exit. Of course, the exhaust system would have to be larger at that point, with higher flow mufflers, but I'm wondering if there would be any benefit to this?

Actually there is an exhaust scavenging system that can be used for evacuating the crankcase. The tubes are typically welded into the exhaust pipe right after the manifolds or headers. It's not the best solution but it does work to a certain degree. Here's an example:
The psi of the exhaust would exceed the psi in the scoop's intake, such that air would be coming OUT of the intake, not IN. In other words, you would only have created another outlet for the exhaust gasses.
