Volvo noise when accelerating from dead stop

Sometimes, when I take off from a red light or stop sign, my car makes a thump. This feels as if it is under the car, not a transmission shift noise. It would seem to me that it has to do with exhaust or fuel??? I am guessing. Any suggestions?

Broken motor mount?

Or possibly the sub-frames.

Thanks for the comments. I will have them checked out.

Check the exhaust hangers, sometimes they’ll rust and break and the add’l movement of the exhaust pipes can cause this problem.

motor or trans mount?

Solved. Needed bushing. Thanks!
