Just go underneath your car, and rip it off.

Notorious23CL

haha....

is there a chance that it's your catalytic converter? is it under the hood or under the car? if it's under the hood then I dunno what it is. but if it's under the car it could be your converter. My friends trans am made rattling noises too and he fixed it by taking off his converter lol.

i hate rocks in my catalytic converter heat shield......also some inside my side skirts.....for months i just turned the system up and drowned it out........then i pulled the heat shield cover off and dumped the rocks........my poor car, takin a lowered cl down gravel roads....wtf!?

Mr.Fred

Your cat is bad. Something has caused it to break down. Fix it or it will possibly lodge in the exhaust and choke your car to death!

if your cat goes bad... u will feel a significant loss of power. However... the rattling under my car at the moment is the resonator. I asked the honda dealer to check what the rattling was during an oil change i was getting there.

I had this and it was my heat shield....I just bent it so it wouldnt do it anymore...Now i have this Metal on metal rubbing sound when ever i hit the gas uot of gears, nto sure what would cause this....It's not a screeching sound..just like a rubbing sound like brake pads would be hitting the rotor or soemthing, even though thats not what it is, any ideas?

My cat makes the same sound. Removed the heat shield and it was slighly louder. So I figure it's the cat. Bought a hi-flow cat (not test pipe) now I just need to get a catback exhaust system because the high-flow isn't the same length.

see what happens when u tell every Noob to search!

If you burn any oil you could have goo in your cat that is starting to clog it up.

Heat shield will usually start to rattle first though, I've had that happen with other cars as well. The heat shield is so you don't light long grass on fire if you are driving in the country and stop on the side of the road..

When you get a new cat, the plus is you can put in one that's much smaller than the OEM one, and possibly reduce exhaust system restriction.. albeit with a lot of custom work with welding a flange on to the smaller cat. Avoid the Acura cat part. I got a best-ever 35 mpg on the highway with my $90 Magnaflow cat, can't be sure if this is the only factor and it also could be there's a small hole still in there.

I got the same problem too, happend only after driving for about 15 minutes, then everytime i hit the gas it hear that rattling noise. Sounds like it comes from under the right side of the car.

It's your heatshield

qstorm78

Is that something i can simply remove and the rattling will stop? Or is it something that needs to be replaced and where exactly is it?

You can remove it, it covers your catalytic convertor. I just ripped mine off when it started dangling by 2 of the 4 screws and dragging on the ground

That was the first reason why I signed on to this site.

My cat went bad & it sounded like a cofee bean in an empty coffee can being banged around.

OP run your car a lil hard, if you smell a 'rotten egg' smell I garuntee it's your cat. When you let it go bad enough to where all the 'honey combs' inside are deterrierating (sp loL) it'll prolly throw a CEL. Thats what mine did.

Don't go bobo & take your cat off. Thats what stupid ricers do to pollute the world & run around with a CEL. Take your car to a muffler shop buy a cat with an o2 bung & get it taken care of.
