Okay......any help you guys can give would be greatly appreciated.

After I turn my Si off, and walk around the car, there's a metallic popping noise seemingly coming from the exhaust. Compare the sound to having an empty aluminum garbage can, pressing the side in, and having that side pop out. Its not a cringe-worthy sound, but enough to cause moderate concern. Any ideas? Thanks in advance.

all cars ive been around have done this. my best guess is that the Cats are still hot and are cooling down
Thanks for the reply. I should have stipulated that this sound is not similar to a catalytic converter cooling down. This noise is a recent occurrence, not something consistent throughout my ownership. In addition, this sound is louder and far more attention-grabbing than the typical cat-cool cycle sound. I guess a good analogy would be: exhaust popping --->cat-cooling, as gun-shot--->firecracker.

I have a stock exhaust. The only 'upgrades' performance wise are: Hondata Reflash and an Injen CAI. Thanks guys.
