So today when I got home and left the car, I heard a weird "clicking" noise almost like a rattle from the rear portion. Any idea what it is? Its about -4C right now if that has to do with anything. Any ideas?

So here's the video clip of the noise:

was this after the motor completly shut down or just before the rpm died to zero?

 

shut down completely i exited the car and was heading to my front door

 

got my curiosity up on this one now. I havent experienced this one personally. sorry couldnt help. but i will keep checking back to see where this goes.

 

It's most likely your exaust system cooling is causing it, if there is any moisture then that would add to it. It's the thermal expansion and contraction of the materials. I have heard it on my RA and my wife asked me the same question. I am pretty sure there is no harm. I have heard the same thing on other cars as well. In small gas engines it's more pronounced like lawn mowers and snowmobiles. I assure you the designers/engineers counted on it. It might be the cooling of other components but I think I tracked it down to the exaust.

 

happens to me all the time in a bunch of different cars im guessing its cooling like cyber said

 

You mean the noise every car makes when it shuts down?
Kind of sounds like a bunch of rain drops or a dripping faucet for about a few minutes?

Maybe?

 

yeah, Mine varies a bit though. Sometimes there is a lot of noise other times not so much. I wonder if has something to do with weather, combined with how hard I run it. It never sounds bad though. Remember we have really big mufflers (bigger than any car I have ever owned) and twin outputs. I really think it's nothing to worry about.

 

That could possibly it, I guess I'll try to get a sound clip tonight. And if others who notice this similar noise do as well, we can compare?

 

if its exhaust components, it comes from the bolted flanges and espacially overlaping tubes that have been welded together.

 

So here is the video i uploaded, anyone experiencing similar things? or have any idea?

I've had this on both my cars. I was always of the understanding that it's just the car cooling down.

 

The oem exhaust system clicks for hours after I've driven the car.

 

hmmm, should I contact the local dealership about this?

Also, that's weird Google Video no longer has my video :S and youtube wouldn't allow me to upload it

 

No need to take it in. It's a fairly normal event.
