strange ticking noise during cooloff
hey everybody,
i was wondering if any of you guys experienced ticking or pinging noises from your car after shutoff. whenever i drive for over 10 minutes or if i drive on the freeway, i hear these noises coming from under the car. does anybody know what it is and if it can be stopped? initially i thought it was the pinging/knocking noise that's been documented here, but that noise occurs during acceleration. the noise i've been experiencing is almost a metallic pinging noise and sort of high-pitched.
thanks guys, i appreciate it!

Noise doesn`t came from actual catalityc but from sheet metal exhaust and manifold covers. Those covers cracks with age and fatigue, often alround screw heads.
As the sheet metal expands and contracts it generates noise between edges of the cracks and such.
Replacing shields and tightening bolts will take care of the noise if you find it bothersome...

Before getting a high flow cat make sure that it will comply with california laws 
I've heard many peopel recomending them, but no one has posted if they pased a smog check with one.

And Aerostar, here's a funny one for you: I went out with this chick a while ago and had dinner and so on. Afterward we had some drinks and I invited her back to my pad. Once we pulled into the garage and got out of my SC she turns to me and goes, "what's that clicking noise from your car? Is it gonna blow up?"
I just said "don't worry about it" and walked her into the house. That's when the pinging started to bug me

How long does it usually take for this breakdown to happen? Meaning how often would the above service need to be performed before needing to do it again? DIY? I'm comfortable jacking up the car to replace mufflers, braces, ... I just don't know what is involved in this fix. Any help would be appreciated. Thanks.

On the second part I can`t say how often. To many variables
