i would look into the holeshot slip on, the yoshi, scorpion slip- ons. these all are good pipes and sound good with out being to loud. they also hold up for quit awhile. have heard the holeshot 14" comp on a b6 sounded sweet. also heard a yoshi, also sounded good, and the scorpion sounds a little bit more mellow. all are good pipes for the price.
