Bikeman Performance Exhaust Full Velocity / GEN4 850na

This 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 with a mean sound. This muffler has a special thermal barrier and internal packing that keeps it very cool on the outside. You can nearly put your hand on the muffler after running the motor, which greatly reduces under the hood heat! All mufflers are extensively tested on our Superflow 902 dyno to ensure the best performance. . On this model, it was not easy to make the correct back pressure. Other manufactures without this technology will most likely create some sort of power loss. This is why you should trust BMP with all of your exhaust needs. Proven performance that works!! This muffler is extremely durable and is available in high temp black or ceramic chrome for both stock bore and big bore applications.
