    For 2002 - 2006 Touring® 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 2007 Touring model exhausts (previous year bikes were not equipped with oxygen sensors). For 2007 model bikes, ThunderMax® sensors will install without modification. If the exhaust system on your 2002-2006 model Touring motorcycle is not equipped with oxygen sensor bungs in the 2007 location (near the cylinder head exhaust port), 18 x 1.5mm bungs will need to be added to the existing headers, or purchase an exhaust header with bungs installed. Weld-in bungs are listed above. See the video link for tips on installing exhaust bungs.
