i just recently bought a 08 g37s, i brought it to the local dealer and had the exhaust changed due to the rattling noise caused by a broken weld containing to the baffle on the inside. im not sure if i heard this noise before but i now hear a clinging, ticking type coming from the bottom of the car when im stopped say at a fast food drive through where it reflects off a wall or something. it also happens everytime i have been driving and turn the car off, i have heard this sometimes on other cars after they were shut off, is this a normal sound?<!-- google_ad_section_end --> <!-- / message -->

 

You have a 6mt? Mine makes noise if I turn off with the clutch out

 

I have noticed a similar noise on my friend's 350z. I havent paid attention to see if my G does it.

 

NORMAL most folks hear it at the fast food drive thru just keep the clutch pressed and there wont be any noise,,, ITS THE INPUT SHAFT has absolutely nothing to do with exhaust. Its noisy on the G/Z dont worry be happy

 

and also your supposed to keep the clutch pedal pressed IN when you TURN OFF THE CAR

 

It's the 5 speed automatic with paddle shifters, would that make a difference? It's sounds like it would be coming from the exhaust system further toward the engine

 

oh you have an AT then im confused something sounds wrong

 

Im being told that it's the exhaust heat shield, I guess I should call the dealer and make sure

 

oh hahaa...I was going to say mine does that too but I have a 6mt

 

clinging noise? it could be your cat cooling down.

 

Is this healthier for the bearing? I always have it in neutral with my foot off the clutch when I turn off the car..................

 

Dont worry about it, it's metal cooling down.

 

2nd that, it's the exhaust/upstream cats cooling off, my 09 does it after some hard running.
