The mufflers with fixed sonority are supplied with two couples of filters. The filters are placed between silencer and endcap. As option we have created the variable flows, adjustable with hex key directly from the back of the muffler.
MECHANICAL VARIABLE SOUND
The mechanical sound variation is given by a throttle, which can be positioned on the handlebar or below the tank, connected through cables to the valve placed inside the muffler. Acting on the throttle you can change the sound, also in motion.
ELECTRONIC VARIABLE SOUND
The electronic variable sound is provided with a remote control that allows the motor to open and close the valve in the muffler. Available for Sportster, Softail, Dyna, Vrsc and Touring models.
