From what I have found out about the under car cats for our car, they don't work. Why? Because they don't generate enough heat from the engine to make them efficient enough to work. That was the whole reasoning behind Ford putting the cat in front.

I looked into doing this, and the experts said either do no cat, a high flow cat up front or leave it be.

They strongly suggested not putting the cat under the car.
