Personal preference. Some folks love the stock pipes. After-market pipes only improve sound (to some) and add a little performance. Nothing is wrong with the stock pipes, but they are very quiet. My bike came with long off-roads that I had for one year. They are slightly louder than stock, but only slightly. The critical item is to remove the Air Injection (AI)immediately to avoid blue pipes.
I'd wait to hear the pipes you want to buy if the stockers are too quiet. I listened to three different brands before deciding on the Specialty Spares. It's kind of an expensive mistake if the dealer puts something on that you end up not liking, and they're not too generous with refunds.
