The PCX™ (Power Chamber Exhaust) Technology are factually chambered high-flow catalysts. Used to increase mid-range torque for more responsive acceleration off the line. They are positioned downstream for up to 20% less heat at the floorboards / foot pegs and 50% less heat at the collector, to optimize rider comfort over the stock system. PCX™ technology uses a high-flow double-matrix catalyst that improves torque delivery through the mid-range for more responsive acceleration.

Tech tip: Pre-2021 USA mufflers on a 2021-up EU Softail/Touring? 21-up US models, have just 2 O2 sensors in the headers. 21-up EU models (Euro 5 system) have total 3 or 4 O2 sensors, also 1 or 2 downstream in the muffler(s) or in the balance pipe of the cross-over section. Therefore 21-23 US exhaust systems will not fit 21-23 EU models. 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 a downstream O2 sensor connection. Fitment: Softail: 07-17 FLSTF Fat Boy; 10-17 FLFSTFB Fat Boy Lo; 00-07 FXSTD Deuce; 07-08 Softail CVO. (International models may require minor mount bracket modification)
