Ok I have always had a slight rattle (sounds very tin like) from underneth the center of the car, this is after removing the noisy heat sheilding.

But yesterday i removed the exusaust from the cat back and went for a quick drive...damn it was loud and grubley i loved it haha, any way after the fun i put her back together and the vibration was worse.... a lot worse

i now have a rattle across all rev ranges, on full throttle it stops but on full back off it is embarasingly noisy....any ideas?

Could the contence of the cat be loose???
