We all hate them, the rust, they break, and then they rattle. We all know how to remove the ones that bend around the curves of the exhaust, they are a simple 10mm or phillips head away from being ripped out. But what about the welded ones that protect the cats. I have mine rattling now at low RPM and its driving me nuts. How do I get these things off?! I am talking about the second pair of cats not the integrated header ones. I want to remove the rusted broken heat shields but can't see an easy way to do it. Help me out XN!
