SPECIAL NOTE FOR 2012 AND LATER SOFTAILS® – 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 2007-2011 Softail® 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 2007-2011 location, up near the cylinder head exhaust port. If you are retaining the original equipment 2012 and later exhaust headers, 18 x 1.5mm bungs will need to be added to the existing headers in the upper location (near the exhaust port as on 2007-2011 models), with the 12mm sensors removed and ports capped (2007-2011 header pipes with 18mm sensor bungs can used in place of 2012-up headers without modification). Weld-in bungs and 12mm caps are listed above for modification if required.
