For a while now I've noticed sounds coming from my after I drive a few miles.
It usually lasts for a few minutes.

I don't think there's anything wrong but I wanted to check with other owners.

*Sound clip included*

I don't see a sound clip attached, but if you are talking about a metallic popping/tapping kind of noise from under the car after shutting it off... this is normal, it's just the exhaust expanding/contracting as it cools down. :

Ahh yes it's something like a metallic popping/tapping noise.
I assumed it was something related to heat, but never experienced it on my friends' cars.

Everything's fine then. Thanks.

there's a dog barking in your trunk... or in the secret compartment...

^ This.

May not happen to every car out there but it's also not uncommon.

That ticking happens to nearly ever high performance car after being driven

Stainless steel expands and contracts a lot when heated and cooled. That's the sound of all the mating faces, hangers, nuts, and bolts dragging across each other as everything shrinks back. They're microscopic movements that are very noisy for their size.

That sound is coming from the cat. Just about every car does this.

Every forum, every few months this damn question is asked. It's the exhaust cooling, as already stated. Wait till you have a car with a clogged cat, it will ping so much and so long, I had a friend with an sc400 that after 20 minutes of running the cats would be glowing, it ping so fast and so long lol.

WTF? To me, it sounds like it raining in the background. And then somebody's tapping something with a hammer. And then somebody farts at about 16 sec in. Seriously.
