Noise-reducing disc for Big Mo Exhaust systems
Helps reduce DBs on the trail
Fits all our Big Mo's, and the X3 and YXZ Full Systems
Maintain back pressure on N/A's with stock tunes
Achieves semi-anechoic, physical acoustic attenuation through rigid body absorption causing the suppression of longitudinal waves by precise, transverse conversion.
THE WHISPER BISCUIT IS MADE TO REDUCE DB FOR SLOW TRAIL RIDING COMFORT AND MUST BE REMOVED IF RACING OR AGGRESSIVE TRAIL RIDING. IF BIG MO IS RUN WITH WHISPER BISCUIT AT HIGH THROTTLE LOAD DAMAGE TO MUFFLER AND OR MACHINE MAY OCCUR.
