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

  • This new generation version of the Pro Moto Billet silent insert is less restrictive and performs better than its predecessor.
  • Insert fits all new style color anodized "cone" type Pro Moto Billet spark arrestor end caps (Endos) 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.
  • Notes: These will NOT fit Pro Moto Billet's older style polished "snorkel" style end caps. (If your end cap is bright polished aluminum, then you have Pro Moto Billet's older style end cap.) Sound intensity level will vary depending on model, tuning, and exhaust system condition.

Works as advertised.

This insert works as advertised. It reduces the sound output of your exhaust but, as far as I can tell, does not affect the power output of the bike. A good product if you are close to the sound limit at your local track.

Has anyone used this on a CRF250R with dual exhausts? Does just using this on one exhaust lower the sound decibel levels enough to ride in state parks or do I need to purchase two?

You would want to go with both to get the most noticeable difference.

Does this work with a spark arrestor and does it work with pro moto billet end cap?

This is designed to only work with the Pro Moto Billet end cap and is also compatible with the spark arrestor included with that end cap.
