2002 honda civic rattle noise?

My civic keeps making a rattle noise everytime I press on the gas pedal and when I accelerate also when I reverse the noise is louder. Also when I let my foot off the gas the ratlle noise goes away and if the gear is in park and then rev it it doesn't make the noise. Is it the exhaust manifold?

Could be. Could be heat shields could be license plate could be anything. I can't tell you without seeing and hearing it.
