vibrating in rear when applying brakes hard

cudlife

i drive a 2000 lincoln ls v6 that runs miint but everytime im stopped at a light and im on the brakes i hear this loud vibrating sound coming from the rear of the car sometimes it gets louder and a little quieter but its always constant, any suggestions into what it might be

While you're applying the brakes and slowing down or after you're completely stopped with your foot on the brake?

after i've completely stopped with my foot on the brake, then as soon as i lift off and hit the gas it stops immediately

Exhaust maybe?

cudlife

it wouldnt be the brakes? i should just get a new exhaust tho, cuz i just got clamps put on the right one cuz it wasnt even clamped to the hanger anymore and when i'd floor it my exhaust would rattle hard
