Well got it up on the ramp again and checked the bolts ,,,but we found what it was ,,the cat was the problem so we took he front section cut open the cat and seen that the brick inside was broken hence the noise and what a noise ,,so we took out the cat and placed back the piece we cut open and welded it up ,,mounted all back and it runs better than before ....
