Can anyone out there help me,after returning from a weekend trip to a wedding,driving approx 2000 kilometers I have been noticing a whistling noise upon acceleration.The heavier I push it the longer the whistle.I have checked out my CRAB intake not coming from there.It sounds like under the car,very similar to the sound it made when it was 1 year old(warranty covered it),but not sure about now with 80,000 Kliks.Problem then was exhaust.
