SPECIAL NOTE FOR 2010 AND LATER MOTORCYCLES - ThunderMax® includes wide-band, 5-wire oxygen sensors that thread into 18mm x 1.5mm bungs located near the exhaust port, same thread size and location as stock narrow-band, 2-wire sensors used on 2008 and 2009 Touring model exhausts. Starting with 2010 models, all Touring bikes are equipped with a catalytic converter in the headpipe collector area. The oxygen sensors used on 2010 and later Touring models are smaller (12mm threads) heated 4-wire, narrow-band sensors located just forward of the catalytic converter near the transmission. The ThunderMax® sensors must be mounted in the 2008-2009 location, up near the cylinder head exhaust port. If you are retaining the original equipment exhaust header, 18 x 1.5mm bungs will need to be added to the existing headers in the upper location (near the exhaust port as on 2008 and 2009 models), with the lower 12mm sensors removed and ports capped. If using a not-yet-purchased aftermarket exhaust pipe, order an exhaust system for a 2009 model (fitment is the same for 2010-2011 models) and your ThunderMax® sensors will install without modification. If you already have an aftermarket exhaust designed for a 2010 and later model Touring bike, you will need to install bungs as mentioned previously if the system is not equipped with dual bung locations.
