|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.
The P4 PowerTip™ was developed to fill the gap between the P1 and P3 sound reducing tips. The P4 is less restrictive than our P3 but quieter than the P1, reducing sound output between 5-6 dB on most pipes. Power loss is minimal. Maybe used with a spark arrestor screen.
Like all of our other sound suppressors, the P4 is very easy to install - simply unbolt your existing M-7 endcap, drop in the P4 and reassemble.
