My cat heat shield rattles really horribly. I recrimped the edges (good old mole grips!) but within a few days it started again.
The heat shield is also completely corroded away in the middle (like every one I've ever seen). So not only is it rattling, it isn't protecting the cat from splashes, or long grass from the cat, like it should.
Short of replacing a cat that still works fine, how can I cover it up and stop it rattling away?
(And for the pedants amongst you, I am talking about a catalytic converter, not a feline furball generator..)
