noise coming from aluminum ds??

you can really hear the sound in 3rd 4th and 5th.....it will whine down when the car decelerates as well....i was drving next to a wall today and i could hear some sort of light scraping noise from under the car, it kind of sounded like a paper bag under the car....but i dont think a bag under the car will make the whining noise it makes...the noise is obviously annoying

This is may be a stupid ?. But have you looked under the car. If it sounds like a scraping noise the DS may be making contact with the muffler flange or something. Look for grooves in the DS. Peace
