This is a before and after video for the vance & hines competition series 2 into 1 exhaust on a harley sportster forty eight with a joker machine air cleaner. it is also put up on a side by side comparison with my big radius 2 into 2 pipes and xlflow-r air cleaner. there will be more videos and more mods to come.
