Should be able to remove the bolts as long as they don't hold anything to them. Even if there is something attached you can remove them to detach the rest of the shield and then reattach. Either way, removing your heat shield is not what you should focus on, but instead installing a new one. Your exhaust gets really hot and the shield is not just for ...
I just realized that I never followed up on this question: It turns out that the rattle was coming from the connectors holding down the large trim piece that lines the base of the windshield. It's a long piece of curved plastic with vents for the defroster and happens to have the VIN tag attached to it. If you pull this piece (using a wrapped screwdriver ...
My friend has a similar problem in her car and the only thing that helps is putting a thick stack of papers (parking stubs and tickets, mostly) between the dash and the part of the body that's between the windshield and the right window. It's worth a try.
It sounds as if the internals of the cat may have broken loose. The catalytic converter is already broke so you can't make it any worse. The worst thing that can happen is it could the piece that is rattling may break free and plug the exhaust leaving you stranded. I would also ask the dealer if they will cover potential problems of a clogged muffler later ...
I had a mechanic remove mine on my focus (2003) (it was half off anyway) and it's been fine since winter. I think the car got louder though. You might want to check your front coil springs. I thought the problem was the heat shield, but it turned out I had a broken front right coil spring. Fixing that got rid of the rattle. Don't let a mechanic sell ...
You should be able to tell whether the noise you are hearing is rattling, or vibration. They could have very different causes. If you hear rattling somewhere in the dash, then it's probably something in the glovebox or various compartments inside. The first thing I'd do is to take away everything from these and drive around the block for a quick test. ...
Something may have gotten into your air vents. I had a leaf in there and it drove me crazy til I one day realised what it was and got it out with a tweazer. It's worth a shot as it won't cost you any money.
If you take off the heat shield expect your power to drop slightly, as the area under the bonnet/hood will get hotter, which will also heat up incoming air. This is more of an issue on highly tuned cars, but may still be noticeable on yours. I would always recommend getting it replaced, rather than removed.
The vin tag can get loose sometimes. It should be up by your windshield on the left side. They are intentionally not made easy to access. Which begs to question why they would also frequently become loose on old cars but I digress. Because of how hard it is to access I would suggest using some clear RTV on each end to stop it from rattling. The added bonus ...
