    For 2012 and later V-Rod® Models: 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 2008-2011 V-Rod® model exhausts. Starting with 2012 models, the oxygen sensors used by H-D® are smaller (12mm threads) heated 4-wire, narrow-band sensors. The ThunderMax wide-band, 18mm sensors must be mounted in the 2008-2011 location, up near the cylinder head exhaust port. If you are retaining the original equipment 2012 and later exhaust headers or have already purchased a pipe configured for 2012-up style 12mm sensors, 18 x 1.5mm bungs will need to be added to the existing headers in the upper location (near the exhaust port as on 2006-2011 models), with the 12mm sensors removed and ports capped. If using a not-yet-purchased aftermarket exhaust pipe, order an exhaust system for a 2008-2011 model (pipe fitment is the same for 2012-2015 models) and your ThunderMax sensors will install without modification. If you already have an aftermarket exhaust designed for a 2012 and later model V-Rod®, you will need to install bungs as mentioned previously if the system is not equipped with dual bung locations.
