removing heat shield

[tonycarreon]

so last year on a drive back from dallas, my passenger-side rear cat heat shield started to rattle. from what i can tell (and anyone correct me if i'm wrong) there are three retaining "brackets" attached to the cat holding the shield down. has anyone removed the shield without adverse effects? i don't think it's completely necessary since there's the material covering under the trunk area and there's some clearance between the shield and cat.

took it to the porsche shop i use and they said they could remove it and it shouldn't pose a problem. checked all the connections and everything's tight. it just wiggles more than it should.

at some point i do plan on upgrading the exhaust so just looking for a temporary type of fix to stop the ANNOYING noise.

(only at low rpms. anything over 1500 or so and there's no noise, unless it's drowned out by the motor)

Similar problem here Tony but I have yet to isolate it. I will replace the header/cat unit if that is where the problem is. Friend had similar noise and it was the INTERIOR of the cat that was crumbled and rattling around. Now that my part of the globe is beginning to warm up a bit, I hope to be able to get under the car and start tapping around with a rubber hammer and see if I can get the thing to make the noise. If it is just the shields, I think you can tighten them down and stop the noise. Keep me posted on your findings.

The secondary cat heat sheilds are fastened with 3 unique 1/4 turn hexhead capscrews into nutplates. I would just remove the sec. cats 1 at a time & shake to see if something is loose inside & check the heatsheild fasteners to make sure they are secure.
