Is your exhaust pipe loose? Where does it sound like it's coming from?

Hello.. thanks for your help !!
It comes from the drivers side ... I think its coming from somewhere near the brake booster... the exhaust pipe seems to be ok.... as a matter of fact I recently took it to change all the exhaust pipes, from the manifold...that was about a mont after the sound started... I though it would be the problem and changed the pipes, but that was not the problem.. the vibration and sounds are still there...its driving me insane !!!! HELP !!

Maybe the answer

I had the same thing on m 96 cherokee, turns out is was the catalytic converter, the baffles inside the unit had collapsed. Around 2000 rpm the rattle was God awful, changed it out, no more problem. Well, maybe this is the prob, hope this helps.
