Note: The Genuine Honda muffler gasket is a very tight fit inside this muffler. Some minor modification may be required or a slightly smaller gasket for proper fitment. Does not come with the rubber center stand stopper.
Note: May have some minor surface imperfections, mostly around the welded bracket on the back. The discoloration is not visible after the muffler is installed (see photo).
