For 2021-later EU Softail/Touring models, the O2 sensor eliminator plug is required (see accessories)
Tech Tip:
Pre-2021 USA mufflers on a 2021-up EU Softail/Touring?
2021 and later US models only have 2 O2 sensors in the manifolds. 2021 and later EU models (Euro5/Euro5+ system) have a total of 3 or 4 O2 sensors, also 1 or 2 downstream in the muffler(s) or cross-section balance pipe.
Therefore 2021-2025 US exhaust systems will not fit 2021-2026 European models.
The O2 Eliminator Plug (see accessories) allows the 3rd downstream muffler O2 sensor to be disabled, without triggering fault codes.
This will allow the use of pre-2021 US or European exhaust mufflers that do not have a downstream O2 sensor connection.
