Powertip DB Killer / Turndown Tip / Spark Arrestor 

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. 

Whats a DB Killer?

Our P1 Powertip sound suppressor is a recommended accessory for our exhaust systems with M series endcaps. A straight-through sound diffuser, the TBR powertip quiets the pipe about 3-4 dB with no significant reduction in horsepower. May be used with a spark arrestor screen

Our P1-X Powertip sound suppressor is a recommended accessory for our exhaust systems with M series endcaps. A straight-through sound diffuser, the TBR powertip quiets the pipe about 7-8 dB with no significant reduction in horsepower. May be used with a spark arrestor screen.

Our P2 Powertip sound suppressor is a recommended accessory for all M-6 mini exhaust canisters. The P2 DB Killer quiets the pipe about 3-4 dB with no significant reduction in horsepower. The P2 fits all M-6 exhaust systems and its easy to install - simply unbolt your existing M-6 endcap, drop in the P2 and reassemble. 

Our P4 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. May be used with a spark arrestor screen.

*Note S1R systems require the use of our wave washer in order to fit a powertip.
