Okayy, so...my muffler melted a bit of my bumper, and i don't want to spend 90 dollars for a stupid carbon fiber piece, so i was thinking, id get a slab of thin non heat conducting metal and affix it above the bumper, nobody can see, ill have a piece of mind knowing no more melting is gonna happen, and we will all be happy campers!

now.

the only problem is


What kind of stupid metal, does not conduct heat?! =|


and anybody have tips on this?

 

if i recall correctly, copper does not conduct heat right? copper + high heat paint = invisible muffler guard..or a plastic thats high temp. anybody know of ANY material thats relatively cheap that i can use to do this?

 

copper and aluminum are the 2 BEST conductors of heat.
I'm new to cars. Just bought a tC. Dont really know what to tell you to use.
Just stay clear of copper unless you really do want to conduct heat.

this rare type of metal stays cooler than cold.

 

All metals that I'm aware of conduct heat. The benefit you'll have from fitting a piece of metal to your bumper is a material that will not melt and it can wick heat away from the contact point. Think of it like the heat sink for the CPU in your computer or the radiator in your car.

 

Maybe you can use Dynamat Hoodliner?

 

Copper is the right material to use.

Copper is used to line safes because if somebody breaks in someplace with a torch they can cut through the safe. But not cut through copper. In order to weld a hole through copper you need a plasma cutter which is 10 times stronger than a regular torch. Just some back ground info on why to go with copper :D

All metals generally are good conducters of heat. Copper is a good conducter of heat and I would advise against it. imo brass would be best I can think of.

 

All metals are going to conduct heat. A high temp plastic would work or ceramic material. Ceramic coating is used on headers to keep the heat it so it obviously can withstand the temp.

 

dont use metal, that's just stupid...

like steve said, plastic is the best way to go.

 

Thermo-Tec self adhesive heatwrap. Stick it on the cutout above the muffler. Paint the shiny side of the wrap first. Unless you want it to look like you have tinfoil on your bumper.

 

so is it possible to get some thermo-tec and have it painted to match the car for less than a $90 cf heat guard?

 

fiberglass?
its somewhat like carbon fiber

 

how about just wraping heat tape around the muffler?

 

All metals are good conductors. You dont want something that is a conductor of any level.

A very good INSULATOR is air. Meaning, keep a gap between your muffler and your bumper any way you can. If the hot air discolors your bumper further then put a piece of metal in the middle of that gap.

 

^^ correct

Go to an auto store and see if you can buy longer rubber hangers to make your exhaust hang lower from the bumper, or go underneath and see if you can bend any metal supports on the muffler to give you some space.

 

aluminum? It gets hot but does not stay hot

 

That's completely different than conducting heat.

As others said, look at something other than a metal.

 

Galvanized tin deflects heat pretty well. It's often used as heat shields.

But I'd go with the Thermo-Tec. It's made for this kind of stuff.
