Exhaust Full Velocity / AXYS 600 ('15+) Finish:Black even though we supply recommendedThis is a great muffler for those looking to keep quiet down low but like a little bark once in a while! From idle to 1 3 throttle you can barely tell this is not a stock muffler. In the mid range, you will notice a nice deep tone a little louder than stock. When you hit higher RPM this muffler has an exceptionally good tone without being obnoxious. This muffler has a special thermal barrier and internal packing that keeps it very cool on the outside.
