if its from the cats I think you can get under the car and hit the cat with something and you should hear it rattle. When my cat went bad it would only rattle when the car warmed up.

So 1.) cut the cats and leave that garbage inside (it was broken) weld it after,put the car on (Park mode) push the pedal no rattling and the sound Is now loud and good, but... When i drive the car everytime i push it, i heard a strongly rattling mettalic noise Resound behind the loud v8 sound during all time i accelerate .. Any opinions ? Thx

Does it rattle when you have it neutral and rev, then let off, or just when in motion?Rattle when stopped and while driving, your primary cats are going out, assuming that you only removed the two secondaries; if you are completely without catalytic converters, the plastic baseplate that is used to attach the exhaust hangers to the transmission is another big culprit. If that is the case, you can get them for $7 or so at ECS or others. If it does it only when driving, I'd say look at the flexplates on the driveshaft, and transmission mount as well.
