Maybe Exhaust Rattle?
 
When I start my car sometimes, usually when it's cold, I hear a slight rattle coming from under the car. It only last 5 seconds then doesn't come back until the next cold start. I really don't know what to look at. Any ideas?

Cat?

I'm guessing its coming from there. I can't really tell where cus it doesn't last very long.

Might be a heat shield 2. Mine was doing the same thing, and it was the shield on the passenger side. Above the headers.

Alright I'll look there. It's really slight and won't last longer than 5 seconds on a cold start.

Good luck, chasing rattles and squeaks around the S54 is a pita. Hope you pin it down.

most likely heat shields on or around the cat. happened to me as well, quick hose clamp does the trick, but its a mother to get to. good luck
