When I go over sudden bumps such as a pothole, I can hear a "clunk" coming from outside the vehicle when I have my windows down. This is the only time I hear the noise. It is somewhat metallic sounding, kind of like as if the wheel center caps were loose and making a "clank".

Does anyone have an idea what this might be and if it is an issue or not? Hopefully I can just tighten up something and have it go away?

It is likely that your exhaust system is banging into a crossmember or the underpan of the car.
The rubber that mounts the pipes is very soft.

I have the same type noise. It's annoying. Hopefully it is not something that can cause a problem.

I feel your pain as well. I just noticed it a few weeks ago as the temperatures started to climb.

If you think it's coming from the front wheels it might be this -

I had the same problem. I had an rx8 store exhaust that was hitting something when i went over bumps. I had a garage put some hangers on, went away. I have also noticed that when it gets hot out i have a sound coming from under the dash sounds like change rattleing or something . I found that when the inside of the car is very hot their is a clip holding a wiring harness under the dash near the gas pedal that rattles. put some tape on it and no more rattle. Hope this helps.

Can't make out the picture too well, but if I had to guess, the noise is probably coming from the rear left.

Thanks for the tip. It is not all that disturbing to me, since it only happens when I hit a decent bump. Unfortunately around here that is pretty often. But if it's not a big problem, I can probably live with it for a while.
