The Harley-Davidson stock exhaust has been removed and a new exhaust bracket installed. Our experts are ready to install the PowerPro HP 2-into-1 Cobra exhaust system. The exhaust O2 sensors need to be removed from the stock exhaust and installed on new exhaust. Use some copper colored anti-seize to make sure they do not fuse into the pipe. Take your time and install new exhaust gaskets, mount the custom exhaust and tighten and torque.
