exhuats rattle

[Guest Boxhead]

ok guys, when ever im driving and i stop teh car, not switch off but stop, as in at a stop sign or red light.. most of the time a sound comes from teh exhuast as if there is say a screw rattling inside it, sounds very veyr uncool.. have any of you guys had problems like this? i have had the cat convertor off, and a new cat back system chucked on..

when they bolted the exhaust back up they probrably didnt attach it properly and the clips have come loose

or the rubber bushes or whatever they are have come off/worn out

thats all i can think of

i finally got energy and went under car for a look, anyway basically one of the screws for the cat wasnt tightened completely, leaving the metal washer to rattle around.. so its tightened now, problem solved
