I would think that flows would not get any louder because they are a chamber muffler and not a fiberglass filled muffler. I don't have any first hand experience on this though, maybe someone else can give you an answer from experience.

My flowmaster 2 chamber has gotten a bit louder in the last 10,000 miles it has been on. It will be no different for a bit and then one day, it just sounds better. Several others that are around the truck on a regular basis say the same thing. It took about 1500 - 2000 miles for it to get the "good" sound.
