If you have our AXYS 860 big bore then you need to let it breathe with our big bore Full Velocity muffler! 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 without being obnoxious. 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 to ensure best performance. You can see the airflow chart which shows our muffler vs the stock muffler. Correct back pressure is crucial to how the motor works. On this model, it was not easy to make the correct back pressure. Other manufactures without the 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. *Low elevation only (below 6000 ft)*

If you have a 2016 model with ELECTRIC START please read: The battery box design changed for 2016 which will not allow the Full Velocity muffler to fit down into the sled properly.  Trimming of the battery box will be necessary for proper fitment. Please see the image of the battery box and notice the black cut lines.  This is a fairly simple process with a cut off wheel. Your other option is to purchase our lightweight aftermarket battery box. Find that HERE

7 lbs lighter than stock!
