Clunking / knocking sound after engine start
I get a knocking sort of sound while my car is warming up, but it's from the exhaust. It's more of a popping sound, like small backfires or something. It's definitely the exhaust from what I can tell, there's no noise in the engine bay.
Not sure what yours could be though, pop the hood and try to single out which part of the engine compartment or motor it's coming from.

i am experiencing the same exact thing. the exhaust pop which is whatever but the clunk when i start the car. i have about 1800 miles on the car and it had done it since day one. its almost the same sound as the differential box when you shift, like a little piece of metal dropping
I have the same noise. Mine is modded but it sounds more like from the middle of the car back. You can hear a small clunk when you start the car, then about 3-5 seconds after you hear a more audible one. I'm thinking it comes from the gas tank because it sounds more hollow.
To be honest, i get this same set of noises in my es... it always scares me that it may be in the gas tank like a previous person said in this thread. Hope our cars don't blow up randomly some day...
It's not the exhaust if you just turn the key so the electronics are on, you'll hear one in the rear of the car. That's with my car sitting all night without being started. Then when you start it that's when I get the louder one.

And I dont think its a backfire either.
Also, slowly releasing the clutch when accelerating from 1st, there is a clunk sound, too. But whenever I accelerate a little harder, there isnt any clunk noise. Could this be the clutch issue that an X has?!
I don't have the clunk while shifting. I had to put in a Exedy Stage 2 clutch because I burned up the stock one. If you still have the warrenty for that I'd get it checked out at the dealership.
1. when I turn the ignition on
2. when slowly releasing the clutch to start moving

maybe I should record the sound and upload in youtube.
