Thats the case with the exhaust I have on my car (its a mk1 clio though) as its only noticable at idle or very low revs.Quote: Originally posted by The Bear on 29 August 2005
Thats probably becuase the vibration is bigger at lower revs (i.e the amplitude is bigger).
If its a kind of loose rattling it could be just hitting something as it vibrates wider at lower revs.
