What could be the cause for metallic rattle? It kind of sounds like a loose heat shield and it happens only when accelerating, but not always. Revving the engine on neutral or lifting both front wheels up and accelerating doesn't reveal anything. It could be CV shaft also. Then it should click always when turning, but it doesn't. I also suspected the catalytic converter and exhaust flex joint that might have burnt and are now rattling inside, but in this case it should rattle also when revving on neutral.

Any other suggestions or has anyone had the same issue?

Seems to be reproducible with 1st and 2nd gear at 2100-2500 RPM. Might be also with higher gears, but the road noise is too then too loud.
