Softail: 18-20 FXFB Fat Bob 107; 18-23 FXFBS Fat Bob 114 (NU). Requires disabling 2nd, down stream O2 sensor(s) of 20-up EU models
Part Description
Vance & Hines, Hi-Output slip-ons. Black
Matte black. The M8 Fat Bob looks are spectacular and its Hot Rod style deserves a matching aggressive deep tone. This stepped Hi-Output slip-on design is focused to yield maximum horsepower by improving volumetric efficiency. They will address the needs of tuned motors built for high horsepower applications, but compatibility is still excellent with stock engines. Mufflers are matte black with laser engraved riveted badges for a finished overall look. Note: See 562550 for optional quiet baffle. 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. downstream O2 sensor, without triggering trouble codes. This will enable you to use US or pre-2021 EU exhaust mufflers that are not equipped with an downstream O2 sensor connection.
