OK this is it- Im going to jump in here and answer the question-
This is based on cutting open old FLowmaster mufflers that have been on different vehicles-
They DO get louder because they rust- some will rust faster then others depending on condensation, which can vary depending on how often the car is driven, and climate-
A muffler shop owner I know has cut them open because he was also curious, and this is what he found- according to him, the first thing to go on a Flowmaster will be the baffle inside coming loose from rust-
Not all Flowmasters are going to do this, but this is just based on his experience-
Hope this answers everyones questions-
