Depending on how you intend to use the energy you could be better off using the exhaust to run a turbine, or heat water to make steam.
Yes, thermoelectrics are either very low efficiency, using metal junctions, or low efficiency, using Peltier cells, but Pcells melt at much lower temperatures than a typical exhaust system.
They also work off of delta T so to get any sort of reasonable efficiency out of them you need to cool the other side. I've seen someone manage to just charge a cell phone from a motorcycle but the combination of the exposed engine block and a heat sink allowed for good convective cooling on the back side. That would be harder to accomplish in a car.
