Re: thumping noise on accel.

Had similar problem for long time, many attempts at various solutions ... proved to be loose exhaust mount allowed exhaust to contact frame upon accel. When engine torqued on accel, or turning, or up hill when starting from standing or low speed accel.. Produced a loud noise and vibration in cabin.
Hope this helps.
