motor mounts & flex pipe

Hi I just had the motor torque and strut mount fixed and was told that ihave an exhaust leak flex pipe. my problem is i'm still getting a clunk
when shifting into reverse doesn't happen all the time but it is concerning
plan to have flexpipe fixed in the near future. will that take care of the clunking sound or is it something else? don't have a lot of cash to work with right now. thanks guys for any help.

I would check all the mounts and their alignment or you might be replacing the torque strut again. That's what broke the flex pipe in the first place.
