i\'ve got a propa high pitched sqeek/whistle sorta sound comin from under my car. im not sure wat it is but its been suggested to me that it has sumthin to do with the exhaust??
i had to replace the middle section of the exhaust recently with a new silencer. it stopped for a coupla days afta i did that, but then it felt the need to come back. the noise only really happens when i rev the engine or change gear and it happens especially loudly when i turn the engine off..


its really startin to get me vex so if anyone has a good idea of what it is, it would be a great help.

a high pitch whizzing noise at high revs points at a over tightened alt belt, as it cause excess load on the alternator bearings.
