Tech-Tip: Pre-2021 USA mufflers on a 2021-up EU Softail/Touring?
The FuelPak FP4 (part number 942227) allows you to disable the 2nd. O2 sensor in the muffler, or in the balance pipe of the cross-over section, without triggering trouble codes. This will enable you to use exhaust mufflers for earlier/US models that are not equipped with an O2 sensor connection.
