Do your part in keeping noise levels to a minimum by adding one of our new style turn-down silent inserts to your spark arrestor end cap.

Insert fits all new style color anodized "cone" type Pro Moto Billet spark arrestor end caps and reduces the exhaust note by 2-4 decibels for a more acceptable sound intensity level.

Requires a Pro Moto Billet spark arrestor to install. Decibel levels will vary depending on model, tuning, and exhaust system condition. Will not fit KTM minis.
