    Rattly exhaust! help??

    I've got an Astra G 1.8 and have recently fitted a sportex centre section whilst keeping the standard backbox, when the car is cold and i accelerate i can hear a sort if rattling noise between 2500 and 4000 rpm when the exhaust/engine warms up the rattle is hardly noticeable but still there when listening carefully.
    Any help/advice appreciated.

    could be the back box baffles have come loose but are expanding when warm and quietening down, or could be just the fact it is a sportex, i really do hate them. they are nowt but trouble. incidentally the standard back boxes sometimes have trouble coping with straight through centre sections.
