Could some in the know please post of copy of this GM document as mentioned in this quote from another thread related to the 2005 / 2006 exhaust droan:

2006 LBZ CREW ... 1800 miles ... droan/moan since day-one at about 1750 rpm ... cool to cold climate ... 5000-7500 feet elevation.

Took mine in for a dealer look-see last week.

Dealer acknowledged problem with sound, contacted GMC and ordered parts per DOC #1730582 to weight exhaust system.

Truck goes in later this week for the fix ... We'll see what happens and post results.
In my quest to rid my truck of the exhasut droan I had these exhaust dampner weights installed on my OEM 2005 exhaust, but like an idiot who wasn't thinking, when they installed the 2006 style exhaust on my '05 truck (as per a GM bulletin concerning the droan) I left the weights on my old exhaust. Now, according to the above quote it looks as though GM is stating to put them on the '06 exhaust also.

I'd like to see the document to be able to confirm this.

Thanks!

Rob

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

FYI - Mines a crew cab. According to this, weights don't help - exhaust must be replaced, which was done already
