The black magic gibson muffler comes with everything you need except the thru hull exit fitting and the silicone coupler, clamps, etc. Also you have to cut your jpipe off to 1/2" below the pisser holes to fit into the muffler. I like mine and recomment it. If you are going from a stock water box you would see close to 10-150 rpm increase. If you are going from a shorty water box you would only see about 50 rpm's. The sound is awsome.
