MagnaFlow exhaust such as # MF15778 has an aggressive, throaty sound. I had a set on a Grand Prix GXP with the same 5.3 liter motor (see video link). Now in that car it did have a drone inside the vehicle but so did the stock system so it didn't bother me. On a truck though the distance is greater from the cab to the exhaust so it likely would not be as loud in the cab of your 2004 GMC Sierra especially with a side exit, single pipe. One thing is for sure, it will sound good. I haven't heard a MagnaFlow system yet that I didn't like!
