Most people just like the change in sound. One issue to watch out for, is the effect on the performance. If you free up the exhaust flow, it can increase high end performance, but at a cost to the low end performance.
The big issue most have, is that certain setups will result in low frequency drones at highway speeds which can get on your nerves, or make you drowsy.
