ok this may sound odd but my dealership took off all my dynomat sound dampner. Well they said its not stock and i must of put it in. Sooo i need a part number for that stuff so they can put it back in becuase with out it my car is LOUD inside.

 

Why did they take it off??

 

becuase my sunroof headliner cover got cought in it ive called GM and they wanna call the dealers

 

...LOL. Dynomat is not stock. Nor a GM product.

 

i dident say it was dynamat it said it was like dynamat

 

Not to be picky or anything but, actually you did say it was Dynomat.

 

I manage a collision center and can tell you that there is no GM part number for that. They have contracts with 3M, PPG, Dupont and others. Whoever there contract is with determines what is being used.
