I have recently started to hear a sort of metallic fluttering sound coming from the rear right hand side of the car. It is mainly apparent when I'm in 1st thro 3rd gears, between 1000 - 3000rpm. Although it now seems to do it when the car is stationary and you just rev it. It is really apparent when the sound can bounce off a wall upon acceleration. I have read about this in the past on one forum but an in depth search has come up blank. I think it is something to do with the exhaust. Can anyone help?...........Oh it's a 2001 Boxster S with 33,000 miles.
Thanks
