FMF Racing does offer select items for replacement parts on your existing muffler. We offer end cap kits, decals, inserts and aluminum inlet sleeves. These items can be found by CLICKING HERE. We have a lot of customers calling into ask why we do not offer the outter shell or mounting bracket to our canisters. The reason for this is because all of our canisters and mounting brackets are hand-made together and cannot be sold as individual items. For 2-stroke we offer replacement end cap kits which can be found by CLICKING HERE.
