The OE mufflers are not going to rot out, rust away, or fall apart under anything like normal use. IMO, the stock pipes both look and sound very good.
At the risk of starting an argument, installing aftermarket mufflers will not provide any noticeable power gains, at least not by themselves. Going aftermarket can shave a couple pounds of weight, provide some bling, and make more noise. If installing louder mufflers makes someone happy, if it improves their riding experience, that is a Good Thing for them.
I like Quiet. My OE mufflers were quiet and the FJR/Yoshimura mufflers I have now are still Quiet. But my bike is no faster or more efficient.
Never run out of ideas, traction, and real estate at the same time.
