    Shuddering exhaust when switching engine off

    Whenever i switch my cars engine off (1.7 DTi Y17DT) my exhaust shudders horribly and bangs against something, i think its a plate between the exhaust and fuel tank? (heat shield?)
    Its an aftermarket (Sportex, i believe) mild-steel straight thru cat-back system.
    Any idea why it does this, and what i can do to sort it out?

    Ta

    have a good look underneath and find out where it's banging. either the heat shield has corroded and come loose or the exhaust rubbers are too short making the exhaust sit too close to the car. when i fitted my backbox i changed both rubbers as it was hard up against the back panel and the bumper with the original rubbers on.

    Its on the original rubbers. So might it be worth getting longer ones then? If so, what ones?

    Get some escort rubber hangers from Halfords (They are the ones they stock in most of their stores).

    They are only £1.62 each and fitted a treat to my coupe and help pull the exhaust a bit lower and tighter

    Lol, no worries. Sorted it out at college anway. Turned out the exhaust system was sitting too far back and was banging on one of the heat shields. Got it on one of the ramps and moved it forward a bit.
