When does it rattle? If it rattles when coming off the throttle, it is probably your catalytic converter has broken up. The rattling inside is the ceramic innards all gone to shot. Expensive. Alternatively, get a de-cat pipe and up middle finger to MOT man/woman.

You need to get it up on a ramp and tap it until you have issolated the noise. Possible that one of the centre silencers has failed.

What engines in your car? my '99 sport does this altho its more of a rasp than a rattle (im not even gonna go into the rattles) it only happens at a certain rev range,and is doin my tits in 
its defo an exhaust prob, manifold i think
ive had mine up on a ramp and all i could see moving/vibrationg was the bottom engine mount squirming when you hit the power.

check your heat-shield on your cat, it could be that this has become loose over time

its proberly just the internal baffles of one of the silencing cans. My kwik-fit (I know  ) has broken twice now it was random as well because the broken parts must have been getting logded stuck at some points
