Bgood,

My son has the stove pipe fiberglass rope on his bike, with the V&H.
I have stock exhaust. Here is my take on his noise level.

Sound level of the V&H with their packing is a good bit louder than stock.
Sound level of the V&H with their baffles completely removed is obnoxious.
The fiberglass rope can be used to create any sound level between these two.

Your mileage may vary.
