Lot of air noise coming from under the hood especially when cold. Sounds like the header tubes make it a lot louder. It is isn't deep sound but more like an air hose spraying air under the hood. Doesn't sound that great. Anyone else had this problem with the Pacesetter LT's?

 

Is there an exhaust leak around the header gaskets? Most people get them at one point. If they are leaking you should see small black marks on the gaskets/headers.
