Hello there, i have a 2009 gts....

Just asking for some input in this issue.

It is normal to hear cracking noises after shuting down the car? The noise is louder and more prolonged when driving more aggressive. Generally, after 20-35 seconds the noise is gone.

 

These sounds you may be hearing are probably the catalytic converters popping.

This is normal.

 

LOL! Thats called ticking cool. To avoid it, do a cool down drive before u park, but its normal so dont fret. Its like that on all cars

 

Yup! Totally normal, you'll notice any car does that after you park. When metal gets hot it expands, when it cools down, it contracts, you're hearing it cooling off. When you drive harder than normal, everything gets more heat soaked, that's why its louder after you drive harder.

 

Thx for the replies, i was curious because i didnt heard it with my last 2 cars, but anyways, nice to hear it is normal.
