If you are looking for the highest quality muffler for your XX you have just found it. When we set out to make the Big Mo Slip On for the XX we had several things in mind - We wanted an ultra high quality showpiece, we wanted it to make the most power possible from a slip on, we wanted that unmistakable tone that Bikeman is known for and last but not least we wanted easy secure installation. We not only hit our expectations we surpassed them with an easy to install showpiece that has our signature sound along with making an incredible 5.2 hp and almost 2 ft/lbs of power to the rear wheels with no other modifications necessary. We will have tuning available soon to really take your XX to the next level.
