Just wondering how skilled your minds are. Foot on the brake, shift from any gear to anyother, no noise. Driving down the road hardly any throttle at all, no noise, driving down the road W0T or decent accleration, loud thud right under the seats. Whats your guess as to what the problem is?

 

probably torn tranny mount

 

oh your good! My first guess was U- joint but I got under there and was wrong...

 

 

Exhaust banging, like from the Y-pipe not rehung
right when the Flowmaster went on.

 

nah that other guy was right, easy fix though!
