(d) Without an adequate braking device which may be operated either by hand or foot.
(e) Without an adequate and operating muffling device which shall effectively blend the exhaust and motor noise in such a manner so as to preclude excessive or unusual noise, and, (i) on snowmobiles manufactured on or before January 4, 1973, which shall effectively limit such noise at a level of eighty-six decibels, or below, on the "A" scale at fifty feet, and (ii) on snowmobiles manufactured after January 4, 1973, which shall effectively limit such noise at a level of eighty-two decibels, or below, on the "A" scale at fifty feet, and (iii) on snowmobiles manufactured after January 1, 1975, which shall effectively limit such noise at a level of seventy-eight decibels, or below, as measured on the "A" scale at a distance of fifty feet, under testing procedures as established by the department of ecology; except snowmobiles used in organized racing events in an area designated for that purpose may use a bypass or cutout device.
