I am in the middle of Dynamating my car, and when everything is out, I noticed that this little flapping thing makes alot of noise. Should I dynamat over it? It is annoying... Let me know what you all think.

 

If it is a vent I would not recommend it. The factory puts vents in like this for when you close your doors the air has somewhere to escape inside the cabin. Otherwise when you close your doors the windows would bust out due to the amount of air pressure.

 

It allows you to sit in the car with all the windows shut and the vents closed and not suffocate. Heh.

 

Yeah, i wouldnt cover that up man... my $.02

 

Could you put a enclosure over it and run some hose up into the cabin? That way you can have your cake and eat it too...

 

that is what I am doing.
