Bypass or PC?

When I added an FBF crossover to my bike it did get a little bit louder, but the increase in noise was not nearly as significant as going from stock mufflers to straight-through mufflers like your Mistrals. IMO the elimination of the 4k rpm torque dip that the V11 has with the stock crossover was well worth the slight increase in noise over the stock unit,

you need aftermarket crossover!
