link doesn't work
^^ no link. but if its a rattle that changes with engine RPM its very likely, I had some aftermarket cats that kept shaking pieces loose and they would make some pretty loud rattles
This should work http://www.youtube.com/watch?v=zOP__...ature=youtu.be
I am not an expert by any means on these vehicles, it sounds like a rod knock to me.
SteveC :(
I agree....sounds way more serious than a cat. Mic's don't always transfer the sound correctly but that sounds pretty bad IMO.Quote:

Sounds to consistent to be a cat. I had a cat blow out on my SS and it was a more inconsistent rattle
The car drives fine. I have an appointment with the dealership on Monday because the Cats in my car are still under warrenty. Also, when I bang on the right cat with a rubber mallet it replicates the noise. The car only had 27k on the clock.Quote:

Typically an engine not running correctly is what causes them to fail prematurely.Quote:

Both of them?? Wow..at least they're covering the cost
Yup the sound your car and mine were making can be confusing as it sounded like the engine is/was coming apart on mine aswell.Quote:

Too bad I had to cut up a perfectly good exhaust to find out.:suicide:
Just was a general statement. There is/was a warranty claim issued for our cars about premature failure for the catalytic converters.Quote:
