Yo! When I start up my ST, I hear a rattling noise like a aluminum or something from under my truck. I think it's the heatshield on the exhaust. Any other suggestions, and fix method please....
Tin can noise!

Sounds correct....
Take 2 long hose clamps put them together and clamp it back on tight...
I don't recommend ripping it off...

top and bottom of every catalytic converter, SO you technically may have eight shields...

yes, but only 1 of them may be making noise...... And i don't know what size clamps you need. depending what you have yo may need 4 clamps, OR 1 long one..

Might be catalytic converter innards loose and shaking around. I had a Daytona that had this problem--I had to change out the converter because the noise drove me nuts.

I got this same noise, but I get the tin can noise when I am driving... I did a walk around banged on the muffler, and I don't hear anything that sounds like that. I only hear it when driving.. Any ideas?

Gavin, that is possible,.....
Kirk, when the truck is cold, lay under the passenger side front door and take your fist or a rubber mallet and tap the exhaust or cats with it listening for the noise....

Does it matter if the outdoor temp is over 110? 
i live in Phoenix... Anyway its exactly a tin can sound, but I hear it when I am driving especially when I go over a bridge and the sound reflects off the walls.. But it is noticablely a tin can sound, I took a screw driver and stuck it in the muffler to shake it and still nothing.. I will try banging on the exhaust or cats.... The sound even almost sounds like a little bell is ringing under the truck, I was thinking it might be bearings but I am not sure if bearings make those noises?

Could be a broken sway bar link, or something else....
Take a look around. IT even could be the engine pinging or the timing chain rattle...

Are there any other symptoms to a timing chain going out? I would hate for that to happen.... I am heading to the hills in a couple weeks....

Todd,
I was out there a while ago, and listened real close when i am at a stop and give it a little gas I can hear it, not as loud as when I am going 60 but i can hear it.. Sounds like in the exhaust system somewhere.

Sounds like the way our cats did before all four of them had to be replaced. It's not going to hurt to have them checked out.
