[kie1an]

hi , since having a new exhaust fitted back in january time i have been getting a horrible vibrating . rattling noise which comes from the rear left hand side of the car , the noise come whenever i give the car any gas . any ideas what this could be . i was thinking a bolt or something how it was mounted . i would love to fix this !!! i wouldnt have any complaints about my clio then ha ha

could be the baffles in the back box are gone or exhaust hitting the heat shield?

I think heat shield mate, they rattle like mad when they brake loose
