loose heat shield? It may also be not loose but just too close to exhaust. The heat shield above the back crossmember will rattle if too close to the vibrating exhaust. It's hard to tell in the video. Does it also make the noise in park or nuetral?

Found this thread while searching the forums for this particular issue so please forgive me for bumping such an old topic. I have a 09 Z with a little over 85,000 miles now making the exact same noise in the video maro posted. Sounds like a truck when it takes off. It only happens randomly so it's hard to mimic but I noticed it only happens in gear at low rpms. Has anyone else ever had this issue and figured out what was the cause?

I am in agreeable state with you sir! The cross member must be bent up a bit and needs to be bent down OR the exhaust is pushed to far down and under low load or downshifting is causing the Y pipe to vibrate more then usually hitting the cross member. When I switched to downpipes this same issue happened with me, had to press the cross brace down a bit to give more clearance, otherwise overtime I accelerated or downshifted it rattled bad.

Hope this helps!

Everything seems fine under the car. Nothing bent or anything. I have a stock exhaust too so nothing was ever changed either. Was thinking maybe something with the engine or transmission maybe? Only hear it randomly so it's hard to pinpoint.

It definitely doesn't sound right to me. Almost sounds like it could be a leak at the exhaust or intake manifold, or maybe in the EGR valve system.
