Systems, Mufflers, Headpipes, Gaskets and Brackets

An XS650 restoration project just isn’t complete without a properly fitted exhaust system. Mikes XS can set you up with an XS650 café racer Norton-style slip-on muffler, megaphone bell-end style muffler, café muffler, or other style-suited system. XS650 chopper exhaust options include the cigarette-style dresser muffler, the 15- or 24-inch slash cut muffler and TC Bros Choppers XS650 exhaust kit. Complete your bobber restoration with a 16-inch turn-out muffler, or get the right look in the dirt with XS650 tracker options like the upswept trumpet muffler or upswept megaphone bell-end muffler. We also offer a variety of XS650 exhaust system parts like finned exhaust flanges, 2-into-1 performance header pipes, head studs and acorn/crown nuts, exhaust pipe gaskets and more.
