Robo, JB weld will not hold because Cats DO get extremely hot...The hottest to the touch part on a warm car by a mile. The outside shell can reach 500 F easily. Trust me, I've burned myself on them many a time.
Edit: My brain read Robo's comment as "do not get very hot", making me think him a moron. Oops.
