The popular RC-40 exhaust system has been updated and called the millennium range from the year 2000. All retain the optimum size and configuration. In addition, they now have stainless steel pipes for better appearance and rust resistance. And for the first time ever the stainless steel versions come with a front pipe to fit right onto the collector of lcb header without modification. Front pipes come either "straight through" for use only with the rear muffler, or with built-in resonator for quieter twin-box systems. All tail pipes are highly polished with rolled edges. 2-1/4" large Side Exit Muffler. RC-40 muffler with a sporty looking large diameter pipe that exits in the standard location.
