Is the exhaust heatshield neccessary because my car rattles BAD!?
I've just about had it with the rattles under the car. Didn't do it before I put the exhaust on and I'm almost positive its the friggin heatshield.
I've cut small peices off the heatshield which I thought were causing the problem but everytime I go to take it out to see if I fixed it, theres still a rattle.
Some day this week, I'm going to un hang the exhaust and take or cut off 95% of the heatshield to make sure I don't miss anything.
Also when I shift at redline theres something rattling that seems to be in the engine area on the bottom. Any ideas? Only when I redline shift or over.
Oh and if it makes a difference, some of the rattles go away once the car heats up and has been driven for a couple mins. My goal no matter what if friggin takes is to get rid of all the rattles no matter if the car is hot or cold. No reason random parts on the car should be rattling.
I tried heatwrapping part of the exhaust that was hitting the side of the undercarriage and it worked for a while then started doing it again.
Also tried kartboy hangers and the rattling continued. Hangers didn't stop ONE rattle. Actually they did for a week or two then they came back and where there everytime I drove my car.
Drives me nuts....almost to the point to make me want to get rid of the car because the rattling is so bad and goddam annoying. I seriously can't own a car that sounds so ****ty and I love my car to death.
EDIT: keep in mind that when I wrote this I just got finished working on it for 2 hours and didn't do a damn thing. So I'm kinda venting....sorry.....

It sounds like hes talking about the stock exhaust heat shield, keep me posted. I had some work done about a month ago and have gotten what I think sounds like a heat shield rattle at idle now. Its driving me crazy.

The shield I'm talking about is under the car and covers almost the entire exhaust. From the test pipe to almost the rear axle. About 3 1/2 feet I'd guess.
Looks like a ***** to remove as well...
Anybody have any tips on removing it?

Mine had a horrible rattle after I installed my turbo back. Even though it looks like there is plenty of clearance between the exhaust and the shield, it shifts and makes contact eventually. Mine was making contact on the o2 sensor and near the resonator. There doesn't even have to be contact... The rattle can also be generated from sympathetic frequencies.
An easy way to determine exactly where it's making contact is to rub some thick, dark grease on the edges of the shield and drive around a while. When you get back under the car, look and see where the grease has been rubbed off. Those will be your problem areas. Simply bend or cut those parts of the shield until you kill the rattle.
Also, make certain that if your using a mechanical CEL fix that it is securely tightened. That can generate a rattle that sounds a lot like the heat shield.
