During installation of an aftermarket exhaust, I took off the heat shield for both cats in order to get to the bolts between muffler and cats. I didn't put the shields back on. My engineer mind deemed them unnecessary. They wouldn't be good for heat shields, and the cats themselves seem sturdy enough to resilient against road debris. If I hit anything big enough to damage the cats, I doubt those little shields would help.
Does anybody else run with them off? What about the guys running test pipes?
