Two Brothers Exhaust P1X PowerTip™ sound suppressor is a recommended accessory for our exhaust systems with M series endcaps. A straight-through sound diffuser, the Two Brothers Racing P1X  PowerTip™ quiets the pipe about 7-8 dB with no significant reduction in horsepower. This P1X is great for street use, no more worrying about bleeding ear drums and cops. 

Easy to install - simply unbolt your existing M series endcap, drop in the P1x and reassemble. 

Description: Many municipalities and tracks have begun to implement new, tougher regulations that limit the sound output of street bikes, offroad cycles and ATVs. Two Brothers Racing has developed a series of highly effective sound reducing tips which can help you be compliant.
