My Magnaflow did the same thing, worsening as it got hotter. It would also do it in "D" sitting still with the brake on. The problem was contact on the left pipe with the trunk pan. I ended up bending the trunk pan away from the pipe slightly using a brake spoon. Probably not the ideal solution, but it was immediate and cheap.
