Peacemaker ELECTRIC baffle exhaust muflers!Shown on sportster here !
This great innovative exhaust sytem, has a silencer with a diverter valve, the exhaust gas is diverted through the baffles, giving a quiet purr and normal power, somewhere in between, up to straight through, (i.e no baffles) giving you maximum power and a sound to die for!.
The diverter valve is activated by a switch mounted on your handlebars, this controls a small actuator motor that is mounted discreetly on the bike.
