We designed Endos as an economical way to convert your stock muffler into a U.S.F.S. approved spark arrested muffler. When the spark arrestor screen is not required—such as at the MX track—simply remove three machine screws and take out the screen. It’s as simple as that. Each end cap is machined out of solid 6061 aluminum and installs quickly and easily.

Key features:

• U.S.F.S. approved and engraved accordingly
• Includes removable, replaceable, screen type spark arrestor
• Color anodized removable end cap nozzle
• Hard clear anodized for durability and protection from the elements
• All hardware included for installation

Each Endos spark arrestor includes an end cap assembly with color anodized removable nozzle, a spark arrestor screen, and all required mounting hardware. See Installation Instructions for model specific installation requirements.

Fits the CRF150R 2007-10 models only.

Silent Inserts
Help keep riding areas open by adding one of our Silent or Ultra Silent Inserts to your spark arrestor end cap. Our Silent Insert reduces the exhaust note by 3–5 decibels and the Ultra Silent by 4-6 decibels. Both result in more acceptable sound intensity levels.

NOTE: Sound intensity level may vary depending on model, tuning, and exhaust system condition. Silent Insert is shown below along with our replaceable spark arrestor screen.

To add a silent insert to your order, simply choose the Silent Insert you would like from the drop-down list below and it will be added to your spark arrestor end cap purchase.
