I own a vauxhall corsa on which the exhaust knocks badly when i have passengers in the car in the rear seats. Any ideas on what would rectify this problem???

As this only happens while you have a full car,i think it is the rear end of the exhaust knocking on the bumper.Try adjusting the rubber fixings on either side of the back box,they usually have a little play in them.If looking at the rubber supports one may have even broken.Hope this helps.
