awful sound when hitting bumps - cant determine the problem

i didnt remove the torsion bar during this process. also the noise started maybe 2 months ago out of nowhere. i can see that the exhaust can rub on the frame at times so to test things i removed the exhaust from the header back (so no way for exhaust to hit the frame) and went for a short spin. other than being obnoxiously loud, nothing changed. i really think its in the suspension/wheel area somewhere. just not sure how to determine the cause. i can also "feel" cruncking on the bump rigt beneath my ;eft foot on the floor. not sure if thats the area of the problem but i def feel it there. floorboards are solid. hoping the frame isnt cracked. i will check motor mounts but they were fine as of the other day. i can hear/feel the issue at literally any bump from 5 to 50mph and i just dont want to drive the car until its figured out.
