To install the endcap all that you have to do is drill the rivets out of the stock endcap, pull it out, slip in the new Pro Moto Billet endcap, drill rivet holes in the new endcap, and rivet it in place.

This spark arrestor endcap uses a removable, U.S.F.S. approved, screen type spark arrestor. The whole endcap assembly has been U.S.F.S. approved, and is engraved accordingly. All hardware is provided, but you will need a drill and a rivet gun.
