Clicking metallic sound under the car after its warm up

[FXist]

It sound like heat seal to me, only occurred when I drove the car for a while, and still clicking after I step out of the car......sound like heat seal to me, what do you guy think?

perfectly normal... it's the exhaust system cooling off.

but its happen even when i am idling.....so annoying, i dont hear any of this sound even on my MDX or my previous rides...maybe after turn off..but not while driving

catalytic converter rattling?

I don't think so, sound metallic, does your ex make this noise when you shut off and cool down?

[XIS]

sometimes it does...after very spirited driving, I hear a few little metallic noises creaking/ticking for a few minutes...but I don't think I hear it while it is driving or sitting at a stop light.

I agree here. I hear "metallic clicking" noises at random intervals within a few minutes of parking the car. I just chalked it up to thermal expansion/contraction of some of the thin metal parts under the car and their junction points. It's usually not loud enough for me to hear while idling; but I think I can sometimes hear it when I step outside while the car is warming up.
