If the heat shield becomes loose, damaged or broken, perhaps due to loose hardware or damage from rust, it will cause the heat shield to vibrate and produce a rattling sound. The rattling will be most prominent at low engine speeds, and may change in pitch or tone according to engine speed.

Stainless Steel
Also to know is, Can I remove exhaust heat shield? Some don’t see much use for a rattling heat shield, so they simply remove them and discard them, but this can be a problem. Because the heat shields are designed to protect other car parts from the extreme heat of the exhaust, removing them completely could cause premature failure of other components or even fire.
Subsequently, question is, Is a heat shield covered under warranty? The heat shield does not sound like it is covered under the corrosion portion of the warranty however since it is not a “outer-body sheet metal panel… that someone can see when walking around the vehicle”.
Also, Is aluminum or stainless steel better for heat shield?
Stainless is often used for heat shields, it conducts even less heat than “regular” steel, it can tolerate more heat than steel or aluminum, and it doesn’t rust/corrode as heated aluminum or steel will. My theory is the aluminum will pass more heat than the steel. The ability to radiate heat is measured in emissivity.
How do I fix my exhaust heat shield?
Is exhaust heat shield necessary?
The short answer is that it’s not as necessary as the main sheet guards, but additional shields can keep the driver and passengers more comfortable and save you money on replacement lines and inefficient use of fuel.

Do you need a heat shield for a cold air intake?
Proper heat shielding will decrease the temperature of air into your engine whether you’ve installed an aftermarket cold air intake or still have a stock system.
What can I use for a heat shield?
A brick, stone or tile heat shield is equally effective but in a different way. These dense materials absorb lots of heat and gradually release it as air circulates around them. The simplest masonry heat shield is a cement board that is separated from the wall by one-inch ceramic spacers.
How much does it cost to remove a heat shield?
The parts, which are just pieces of sheet metal and a few bolts, should cost about $160 from a Honda parts department. And the job takes about an hour of labor. That means you should pay somewhere between $250 and $300 to have this done. So you might save half by shopping around, Liz.

Can a heat shield fall off?
All metal exposed to the atmosphere corrodes, but heat speeds up the process, so clamps, bolts or welds can rust to nothing, leading to a loose heat shield. Vibrations can weaken the metal, causing a heat shield to fall off, rattling against the exhaust or some other part of the vehicle.
Why does my heat shield rattle?
If the heat shield becomes loose, damaged or broken, perhaps due to loose hardware or damage from rust, it will cause the heat shield to vibrate and produce a rattling sound. The rattling will be most prominent at low engine speeds, and may change in pitch or tone according to engine speed.
What metal reflects heat the best?
Which Metals Conduct Heat The Best? As you can see, out of the more common metals, copper and aluminum have the highest thermal conductivity while steel and bronze have the lowest. Heat conductivity is a very important property when deciding which metal to use for a specific application.
How much does it cost to fix a heat shield rattle?
It’s just a couple bolts and some sheet metal, but can become a headache. If you take your car to the shop, the parts will be closer to $150 and it should take about an hour of labor. The total bill should be about $300.
