Not that I would do anything to disable an emission system component but the 3rd converter is easy pickings with the cat-back removed.

I don't know about other years but the '11 does not have a resonator on it, just 2 cats close to the manifolds and 3rd after they merge. If someone were to remove the cat-back, beat the guts out of the 3rd cat with a hammer and pry bar, and then start the truck, it would blow chunks of the converter 20'. Like I said, IF someone were to do that.
