Rattle Sound After Reven Engine

[njd]

I notice while stepping on the acceleration while in park, I hear a rattling sound. Can someone help?

Although I have an M6S, I've noticed a little rattle as well. I'm almost sure that it's coming from the exhaust. It's not loud, and seems to go away after the car warms up. Maybe it's your exhaust?

In the M6, the throwout bearing will give a rattle type noise. Pretty common, and isn't harmful.

If you still have factory cats.............the honeycomb may be loose inside :)
