What do you have on the bike currently? If you have the stock slip-on & muffler box then it will be an increase in tone and a little bit more sound. The stock muffler box and cats is where most of the sound is hindered. If you don't have the stock muffler box and have a mid-pipe or MJS headers etc... then it will be extremely loud and putting this on there won't help to muffle it down.How's the sound on that at highway speed? Looking for more sound without makin my ears bleed.
