    Full Throttle Growling

    Alright, I got a question. When I go under full throttle and it is reving at about 3500. Behind the front seats there is a growling noise. It starts at the back of the seats and the higher it revs it slowly shifting farther back. I have had the rearend rebuilt twice and is silent at all speeds. I have a flowmaster muffler and cat cut outs. Any advice?

    Exhaust pipe touching the body under load, most likely.
